You BetArsenal look like the selection in the weekend's big match
Blues might be early pacesetters, but they are showing signs of fragility ahead of derby

Arsenal v Chelsea is the grandstand opener to the Premier League weekend and, with Manchester United v Tottenham to end the night, there should be entertainment from start to finish.
Arsenal's visit to Stamford Bridge was one of the games of last season, as the Gunners ran out 5-3 winners, and a good start to this season for them promises another exciting spectacle - certainly better than the goalless draw at the Emirates last season.
Chelsea are the early pacesetters and are one of four unbeaten teams - a group that also includes Arsenal. This is the biggest test so far for Chelsea, who have played four of the bottom eight in their opening five games, and there are some question marks.
Eden Hazard has brought much-needed creativity in midfield but Fernando Torres still does not look a £50 million (HK$627 million) striker and Arsenal will be pleased by the departure of Didier Drogba, who terrorised them over the years.
In defence, too, there are concerns despite four clean sheets in five league games. The failure to hold on to a two-goal lead against Juventus in the Champions League was a sign of weakness and their lack of pace at the back looks ripe for exploitation by Arsenal.
The Gunners have had a tougher opening set of games, which makes their good start all the more impressive.
