Chelsea-Arsenal: live online preview
There is still plenty to figure out in this season's Premier League, as you would expect after a handful of games, but two sides with increasingly worrying and soothing aspects to their season so far face each other on Sunday at Stamford Bridge - kick-off at 14:30 CEST - looking for answers during a brief but difficult spell.
To make matters more interesting, it's a London derby and with the likes of Manchester City and Manchester United setting the pace atop the table, neither Arsenal or Chelsea can afford to lose. It might come down to a matter of how well you perform against the bigger clubs and how much damage you can inflict on them when points are being tallied at the end of the season.
As Chelsea manager, Antonio Conte, says: "This is a massive game when you play against Arsenal. The same against City, United, Liverpool, Spurs. There are six top teams and when you play it is a massive game. We have to fight and play against a rival.”
After a mini-meltdown to start the season, which saw them lose against Burnley with two men sent off, Chelsea have regained a slice of the form that took them to the Premier League title in Antonio Conte's first season in charge.
After a summer of discontent, the last thing they needed before the transfer window shut was a loss to start the season. They have responded well and in a world of football that is growing increasingly frentic and fickle, a run of good results has largely forced the unhappy Conte and unstable squad narrative to die down. Wins against Spurs, Everton, Leicester and a thumping of Qarabag in their Champions League return have certainly not hurt.
Conte, however, is uninterested in the plight that Arsenal find themselves in, "I don’t care about Arsenal’s situation, I care about Chelsea’s,” Conte said in his pre-match press conference.
“They will solve their problems, we will solve ours.”
Conte also believes that if his Chelsea side keep their discipline, they can win. "I hope to finish the game with 11 players, because in the last two games, FA Cup final and the Community Shield, we finished two games with 10 men," he said. "I hope this. Then during the game I think the best [team] wins."
The Italian almost has a full squad to chose the starting 11 and subs from as Eden Hazard works his way back from a broken ankle and Gary Cahill returns from suspension he picked up against Burnley. New signing, Danny Drinkwater, will miss the game and won't be able to play until October.
Potential line-up: Courtois, Moses, Azpilicueta, Luiz, Rudiger, Alonso, Kante, Bakayoko, Pedro, Morata, Hazard.
Arsenal, a team in seemingly perpetual melt-down, have more to be concerned about. They started the season with a victory but fell to Stoke and Liverpool - in appalling circumstances. On top of that, they missed out on the Champions League this season and their star player wanted out before the end of the transfer window.
Even when things do go right on the field, there are problems on the terraces as thousands of Cologne fans appeared outside the stadium having bought home fans tickets with an hour delay to the game. Arsenal released a statement saying, "Following last night's UEFA Europa League match with Cologne we would like to stress that fan safety was always our paramount concern and informed all decisions made," as they plan to launch a probe into what happened.
Jack Wilshere came on for Arsenal in that Europa League game in what was his first appearance in an Arsenal jersey for close to 13 months and while Francis Coquelin and Santi Cazorla remain out along with a healing Callum Chambers, Wilshere will be looking to break back into Arsene Wenger's plans. Theo Walcott also hobbled off with a calf injury as an assessment of his injury is expected soon.
Potential line-up: Cech; Mustafi, Monreal, Koscielny; Bellerin, Kolasinac; Xhaka, Ramsey; Ozil, Sanchez, Lacazette.
Fancy Nacho Monreal to bag the first goal at Stamford Bridge? A opener from the Spaniard pays out at 41/1.
