At the Bernabeu, we are going to be without the ball for long periods. If Delph's control and passing was better there'd be no discussion, but there isn't an obvious replacement for Silva given that Nasri is not in the squad. For me Yaya is a non-starter, but Delph is a possibility if played as a defensive shield alongside Fernando, or played centrally. Releases Fernandinho to get forward more.I have yet to see it marvin. To me Delph should never be on a football pitch ahead of yaya but then I am not a manager of tactical expert.
