Prior to that remarkable eight-goal thriller in 2011, Arsenal's only victory in ages at Stamford Bridge was under Luiz Felipe Scolari during the 2008/2009 season. Arsenal lost the reverse fixture against Chelsea 3-1 last term and they will be eager to avoid a repeat. It was followed by a fiery Europa League victory against FC Koln, which, to be honest, was more tempestuous off the pitch than on it.
Chelsea were 3-1 winners against Arsenal in their last Premier League meeting at Stamford Bridge in February but the Gunners have beaten the defending champions in the FA Cup final and the Community Shield either side of the summer break.
Given Arsenal's bad record away at sides in the top six - which includes this season's 4-0 defeat at Anfield - it's hard to look past a win for the home side.
Arsenal were charged with a breach of safety and security regulations because of a blocked stairway in the away end, European soccer's ruling body said in a statement. "When the result is not good, anything can happen". The good news for Chelsea is that they may not have to deal with the impenetrable wall of Per Mertesacker this time; Wenger has been curiously reluctant to use the German despite his outstanding performance at Wembley in May.
Gary Cahill will return to the side after serving a three-match ban, and will likely retake his position at the heart of the Blues' defence. It can be expected that most if not all of these three will find their way back into the starting lineup for the weekend.
"That was missing from the last few games. We managed to put some pressure on them in the second-half which led to them making mistakes and we eventually scored", Elneny told beIN SPORTS.
The hardworking Willian is an threat on the right wing as well! Zappacosta scored a stunning goal in midweek, and firmly staked his claim for the spot.
That means Arsenal's injury list is down to just two: long-term absentee Santi Cazorla, and Francis Coquelin who is out for around a month. We still haven't seen what Sanchez, Mesut Ozil and Lacazette can do together.
It was only after the interval, following the introduction of Sead Kolasinac and a change of shape, that the Gunners hit back. "Now we have to move all these situations", the manager added.
Wenger's side have no margin for error as they try to keep up with the early pace-setters in the title race and Arsenal defender Per Mertesacker admits it's essential Sanchez rediscovers his best form. Still, Chelsea probably had the better transfer window of the two, didn't they? "Finally, the course of the match showed that the mixing of home and away fans did not constitute a safety risk for this match".
