Really can't see the problem if the lad wants a release clause built into a new deal, in fact you would have thought the owners would welcome such a move so as to ensure financial reward if Can decided to seek pastures new, how old is he 23 ? so plenty of quality years ahead of him of which we should see the best part of,
i'd be inclined to put a minimum of £80m on his head and if he develops into the player we all hope, we can increase that figure as time goes on, the important thing is he's our player and a pivotal part of Jürgen's plans, so why sell him on, he's a top player and as recent events have shown we are no longer a selling club, we are building, and building something very special,
with Naby imminent the quality in midfield will obviously improve, atm tho, its not too strong, with the Ox to come in also we can see that Jürgen is addressing the issues of a weak central area,
Get this lad signed up asap, and make sure he knows he's a pivotal part of the grand plan, i think we have yet to see the best of him and bringing in players such as Keita will only bring the best out of Can.
