Oscar

Reason to watch: What role and position will he play? How many games will he get?

Oscar was a perplexing signing by Chelsea. He is, quite clearly, an incredibly talented individual, but the Blues' midfield was stacked even before his arrival.

The Olympics have shown the world what he's capable of, and Chelsea fans are very excited about his Stamford Bridge arrival.

It will be interesting to see how Roberto Di Matteo deploys him, which system he uses and how often Oscar will be able to play in his preferred role—attacking midfielder.

He should slot straight into a 4-3-3 like the Italian used last season, and a midfield trio of Ramires, Frank Lampard and Oscar would be fearsome.
