Nemanja Matic
Nemanja Matic has been quietly proving his class since his January transfer to Stamford Bridge, illustrating an innate ability to always be in the right place at the right time and a monumental physical presence too.
How well he can stick with the drifting movement of David Silva and powerful running of Yaya Toure could decide the match.
Ramires
Arsenal have found that when selecting both Mathieu Flamini and Mikel Arteta, the tempo of the Gunners’ play can be slow and tepid.
Chelsea may find the same with Nemanja Matic and John Obi Mikel both passing side to side to each other, and the box-to-box dynamism of Ramires could hold them in good stead to launch attacks against Manchester City.
