Chelsea continue to approach the business of player trading like a child does the swapping of Panini stickers in a school playground.
It's not that long ago, for example, that Nicolas Jackson and Christopher Nkunku were seen as the future of the Chelsea forward line but now it's Liam Delap and Joao Pedro. The club have spent in the region of £190million on those four players alone.
But none of that means Chelsea are wrong to tell Jackson he cannot proceed with his planned loan move to Bayern Munich.
Delap's hamstring injury sustained against Fulham is expected to keep him out of action for a couple of months and Chelsea – back in the Champions League this season – need cover in that position.
