It does matter if they play at home or not. If Chelsea were to play this game away against Arsenal, I think it would almost be certain that Arsenal would win the game, but since this isn't a home game for Arsenal, I think that it is possible for Chelsea to play a better game than they would otherwise. Whether that is enough for a win for them, I don't know. But playing in front of their own fans is at least supposed to be a different atmosphere for them that should help them to put more effort into that game.
Play home or away its not really difference atmosphere for Chelsea because last winning match from away when defeating Burnley, but Arsenal opponent is difference than Burnley with consistency performance and they have more confidence after last match before international break out success beaten defending champion of Premier League teams Manchester City.
Arsenal is as strong as totenham this time. This club is still unbeatable this this time. It sounds non sense if we are comparing arsenal to the burnley caused by burnley was a mediocre team at this moment. I can't wait to see what lineup that will be brought by arteta to the stamford bridge. I expect a slightly change to happen from arsenal's squad. I think that partey deserves to be placed in the starting line up. This guy is really helpful for arsenal. This london derby is one of hottest derby in EPL. I was always aware about how chelsea and arsenal were competing each other.
The gunners need to take full points from chelsea. Chelsea was weak but it doesn't guarantee arsenal to win the game easily against chelsea.
Otherwise, Arsenal have more motivate take first position standings from other London team Tottenham Hotspur, have the same points with lack goals productive I think three points against Chelsea will move to the first position place for awhile due Tottenham Hotspur vs Fulham will play on Tuesday.
Totenham faces relatively weak opponent compared with arsenal. Chelsea was weak but seeing its reputation as two times UCL winner and i can't underestimate it. Arsenal needs to play calmly against chelsea.
Chelsea needs to prepare everything to face arsenal. Three points are very important for the club to climbing up. Chelsea needs to be careful and being very dicipline in this match.
