They won't go with a 19 year old as the starter at Chelsea. Can't see that happening.As said already, not sure that’s true at Chelsea - for all the money thrown around they’ve neglected the DM and only have Loftus-Cheek (off the summer), Zakaria (loan and nowhere near the standard needed) and Kante (finished).
They’ve had to resort to dropping Fernandez in since the WC, signing a true DM will be a key target for them to allow him to move further up the pitch.
