I don't think it comes down to creativity of the players. For most part of it I will put the blame on the manager. When players are playing good we praise the manager so it should be the same when they are not playing good.
If we bring out player by player Chelsea players are better than the arsenal players when it comes to skill but they were outplayed simply because arsenal is better as a group. They press together and attack together. They have one aim and that is to start the game well, outplay and outscore the opponents
