Let's put a bit of perspective on this. It's a 34 year old RB who was being brought in to play second fiddle to Walker. Sure, he'd have played games for us but he was always going to be a back up and a short term solution. Is it a loss? Of course, mostly due him being completely free, knowing what Pep needs and generally because it's another proven winner in the dressing win.
But, focus on the key aspect, he was not our first choice option, never has been, Walker is what Pep wants for this role.
It's not like the obvious first team players who have rejected Uniteds apparent advances (Griezeman, Ronaldo, James R, B. Silva etc) or Chelsea missing out on Lukaku.
Chin up, Txiki will fix it and come the opening day of the season I'm sure we will look back and laugh at how much flapping went on over a 34 year old back up RB.
