Unless they have someone waiting in the wings at the youth level like they did with Pozo last year.
That being said - he needs to take a massive pay cut for it to work here. I honestly think there is a better chance he joins in January of 2017 than this summer. He could slot into a CDM or CB position upon Lampard stepping away. That being said, I would be concerned that he is not quick enough to play here.
They had Jason Denayer ready and waiting to take up the 4th defender space. Then they chose instead to loan him to Galatasaray for a full season. There's no-one else in the club capable of mixing with the first team in CB.
