With 24 bookings in two-and-a-bit seasons, moody Chelsea striker Diego Costa is used to living on the edge in English football.And nowhere is his brittle temperament seemingly put to the test more than in matches against Liverpool.A stamp on Emre Can that earned Costa a retrospective three-match ban. The numerous bust-ups with Martin Skrtel. The forehead-on-forehead confrontation with Steven Gerrard. It doesnt take much to rile Costa but theres something about Liverpool that really fires up the often-pilloried Spain international.So expect plenty of scrutiny on Costa when the two teams meet in the latest Friday-night fixture in the English Premier League, which is the highlight of the fifth round of games.The debate is on regarding Costa: Will he finish the season with more goals than yellow cards? Its a close-run thing at the moment.He is back to his best in front of goal, netting four goals in four games in Chelseas unbeaten start to the league campaign that has seen the team earn 10 points from a possible 12. In the 2-2 draw against Swansea on Sunday, Costa scored both of Chelseas goals and was almost impossible to keep down.Costa is also keeping match officials busy by getting three yellow cards, and ran the risk of seeing those turn into red with a studs-first challenge against West Ham and by throwing himself theatrically to the ground against Watford and Swansea.Costa, put simply, is never far from a flashpoint.If you are in a friendly-game mood then you have no chance, Liverpool manager Juergen Klopp said of Costa. He is a real warrior on the pitch.Theres rarely a news conference with Chelsea manager Antonio Conte that doesnt involve a line of questioning on Costa. Conte says the striker is targeted -- and it is easy to see why given Costas inability to resist reacting to goading by opposition players.Diego is growing in these situations -- in the last game he showed great attitude, Conte said Thursday. He is passionate but I?want him to put his passion into the football in the right way.Its one of the many subplots in what could be a thrilling game under the Stamford Bridge lights, considering the start to the season made by Chelsea and Liverpool.Liverpool has scored four goals in each of its wins over both Arsenal and Leicester, and also gained a point from a draw at Tottenham. Aside from a disappointing 2-0 loss at Burnley, Klopps side has been impressive -- especially the fluid forward line of Philippe Coutinho, Roberto Firmino and new signing Sadio Mane.Only Manchester City, which has won all four of its games, has more points than Chelsea so far this season.And if Costa shows passion on the field, Klopp and Conte are possibly the most animated Premier League coaches on the touchline. Like in last weekends Manchester derby when Pep Guardiola and Jose Mourinho went head to head, there could be as much focus on the coaches technical area as on the field at Stamford Bridge.Here are some other things to watch out for this weekend:---LUIZ STARTSDavid Luiz will make his first appearance in his second spell at Chelsea after Conte confirmed Thursday that the Brazilian will replace injured John Terry at center back.Terry hurt his ankle against Swansea and was ruled out for 10 days.Luiz was signed from Paris Saint-Germain for a reported 32 million pounds ($42 million) on the final day of the transfer window, about 20 million pounds less than Chelsea sold him to PSG for in 2014.---CITYS RUNMan City puts its winning start to the season on the line at home to Bournemouth, having taken its run of successive victories to seven by beating Borussia Moenchengladbach 4-0 in the Champions League on Wednesday.Pep Guardiola still hasnt tasted defeat as City manager.After his hat trick against Moenchengladbach, Sergio Aguero drops out of the team for Saturdays match. He is serving the second match of a three-game domestic suspension for elbowing an opponent.---OTHER GAMESManchester United manager Jose Mourinho will hope a Europa League match at Feyenoord on Thursday doesnt take too much out of the team for a Premier League match at Watford on Sunday.Also Sunday, its: Tottenham vs. Sunderland; Crystal Palace vs. Stoke; and Southampton vs. Swansea.On Saturday, its: Hull vs. Arsenal; Leicester vs. Burnley; West Bromwich Albion vs. West Ham; and Everton vs. Middlesbrough.

Despite the hundreds of millions of dollars spent by a growing number of Chinese Super League clubs in 2016, Guangzhou Evergrande continues to dominate, winning a sixth straight title on Sunday.Luiz Felipe Scolari made it two championships since arriving in June 2015 as the club was held 1-1 by Yanbian Funde but moved seven points clear of Jiangsu Suning in second with two games remaining.Guangzhou has dominated most of the season, helped by Brazilian internationals Paulinho, who scored against Yanbian, and Ricardo Goulart, the leagues leading scorer, as well as a number of top Chinese players.Guangzhou are a worthy champion for sure, Mads Davidsen, assistant coach at fourth-placed Shanghai SIPG, told The Associated Press. This is the sixth title in a row, so no doubt they are still the strongest team in China.Despite the dominance, the signs are promising for the Chinese Super League. The overall average attendance is set to finish close to the 25,000 mark this season, up from just over 22,000 in 2015. Once again, it is the highest in Asia,The fever here for football is something I have not seen before, Choi Yong-soo, the South Korean coach of Jiangsu, was quoted as saying by FIFA. The stadium and the fans, its all huge.Chinese clubs such as Guangzhou, Jiangsu, Shanghai SIPG and Hebei CFFC spent over $400 million in the winter transfer window on stars such as Alex Teixeira, Ramires, Jackson Martinez and Ezequiel Lavezzi. In the summer, Shanghai spent more than $60 million on Brazilian striker Hulk.Choi believes that all the investment will make a difference.The infrastructure is well-established and the management system of the club is well-organized, he said. They essentially have laid out the groundwork for further growth. It is an indisputable fact that Chinese football is developing at an unprecedented pace.The season also saw a number of prominent foreign coaches depart and arrive. Former AC Milan and Juventus boss Alberto Zaccheroni and ex-Brazil head coach Mano Menezes were fired in the first half of the seasoon by Beijing Guoan and Shandong Luneng, respectively.dddddddddddd Menezes was replaced by former Bayern Munich boss Felix Magath, while ex-Real Madrid and Manchester City boss Manuel Pellegrini took over Hebei CFFC in August.Scolari, who has lost just three league games in his time in China, is one of three coaches in the running to be named Chinese Super League coach of the year, along with Spaniard Gregorio Manzano of Shanghai Shenhua and Henan Jianyes Jia Xiuquan.I want to say thank you to the players for their efforts and the fans for supporting us so well, said Scolari. This win was not easy. The league is getting tougher all the time and so it is very satisfactory to win the title once again.Davidsen agrees that standards are rising. We now have six or seven quite equal teams as Jiangsu, Shenhua and Hebei has stepped up this season, said the Dane, adding that big-spending Tianjin, promoted from the second tier with coach Fabio Cannavaro, will continue to invest in the top tier ahead of 2017. Tianjin will probably finish in the top half as they have massive finances.Scolari is expected to leave Guangzhou at the end of the season though the Brazilian refused to comment on his future on Sunday. Marcello Lippi, who led Guangzhou to three championships from 2012 to 2014, had been set to return before it was announced on Saturday that the Italian had been appointed as the national team head coach.The appointment was warmly received as an up-and-down year for the national team enters its final weeks. In March, China made the third round of qualification for the 2018 World Cup for the first time since 2002. One point from the first four games in Group A triggered the resignation of Gao Hongbo on Oct. 11.Lippi will take control of China for the first time against Qatar on Nov. 15. His first activity as the national team boss was to go and watch former club Guangzhou secure yet another title. ' ' '
