If we compare the defense of Arsenal and Chelsea, it is easy to understand that Arsenal's defense is slightly stronger than Chelsea's. Also, Arsenal's attack is very strong this season. They scored 30 goals in 12 matches. And so it is very difficult for any team to stop Arsenal's attack. I would say if Chelsea want to win today, they have to play attacking. It is impossible to win this match if you don't play attacking strategy. But I think Chelsea will play defensive strategy in this match and try to draw the match.
Arsenal is far superior than chelsea in this season. I doubt if chelsea can beat arsenal in this match. Draw might become the possible result just like when chelsea against MU. I hope that chelsea will try to play counter attack strategy. I do like when chelsea was playing counter attack strategy rather than putting fully defensive strategy. counter attack is the most suitable strategy for chelsea since era of abramovich. This time chelsea is also having the same type as before.
It would be good if chelsea can also win against arsenal. That will make arsenal lose points.
