BBC Sport football news reporter Nizaar Kinsella:

For Chelsea, the question of signing Sancho will simply be, why?

They have Christopher Nkunku, Nicolas Jackson, Pedro Neto, Mykhailo Mudryk, Noni Madueke, Cole Palmer, Joao Felix and Marc Guiu in their attack.

But they will argue that Sancho comes at a good price and that he could follow Cole Palmer’s trajectory if allowed to get back to his best.

There is a host of ex-Manchester City back room staff at the club, including manager Enzo Maresca and influential recruitment specialist Joe Shields.

This is a player who, in Maresca’s words, “he knows” and may ultimately fit his system.

Chelsea also like signing players that supported them as children, and south London born Sancho fits that bill.
