Chelsea's squad is overrated, if anyone bothered looking at their squad it'd be fairly evident.
The likes of Willian are thought of highly, maybe because of their £30m price tag, but 4 goals and 3 assists is not exactly an impressive output. Ramires and Matic are a good pairing but neither are a Ramsey. The rest, Hazard/Sanchez, Cesc/Ozil, the defenders etc are much the same too, both in terms of depth and quality. They have a better keeper, Koscielny is better than anything they have etc.
Where they take the advantage over us, assuming Costa is a hit, is in the striking position. But we could minimise that gap by playing one of Sanchez or Theo upfront and hoping they hit it off.
