How do we get to the business end of the Premier League and Champions League with one of our players playing at their best in this position? Fernandinho, Gundogon or Zinchenko seem to be the obvious candidates. Will Fernandinho retire from international football? Will we rotate from the Champions League group matches to Premier League games? Can we get Fernandinho to April and May fresh and in the form of his life? Can Gundogon make the position his own? How many Premier League games could Zinchenko realistically help out with? Is he only likely to get games in the cup? Is there a left field option? With the addition of Mahrez and the emergence of Foden and Diaz could De Bruyne or Silva be converted to this role? Finally there is John Stones. Was Pep serious about him when he said he could play there? Do we have enough cover at Centre Half if he could make the position his own?
