Nah Jam man, you're wrong here. Sanchez is a top player, no doubt about it. I just felt Arsenal relied on Sanchez too much today, most of their attacks sprung from Sanchez, especially those little dribbles from him, he looked dangerous. Ozil is nowhere to be seen at the moment, a shadow of a player from the 2010 World Cup and when he was at Real Madrid. Wenger NEEDS to play Ozil as an central AM, not out wide. He needs to support Sanchez more.
The thing with Chelsea is that, when things aren't going our way, Hazard will suddenly come alive and make a quick dribble past 2-3 players and suddenly the momentum is with Chelsea's. And then players like Fabregas turn up, and Costa turns up to finish the moves off. Arsenal don't have that killer switch, that can suddenly the momentum towards them. Sanchez is their best bet for that, but he's certainly no Hazard when it comes to dribbling and producing a goal-scoring chance out of nothing.
