Delph will be played, centrally, on a decent number of occasions. We've got Yaya, Fernandinho, Fernando and Delph, all of who will be used centrally, in a form of rotation that isn't fully clear at this point. As out new formation(s) seem to be 4-5-1, or 4-3-3 depending on the situation, we need more midfielders than strikers this season, born out by us allowing Jovetic and Dzeko to leave, and signing no-one else who would be classed, predominantly, as a striker. Delph will get his opportunities.
