Sure but you’re talking about changing our formation to go even more attacking when we are chasing the game. In that scenario and the position you’re suggesting playing Sanchez in then defo he’d be an asset. However we were talking, or at least I thought we were, of whether Sanchez could do a better job in central midfield than Gundogan, B.Silva or Yaya... which he couldn’t! Sanchez doesn’t have the attributes in his locker to be a successful central midfielder. Could he stand in and do a job there if there was no one else, sure. But he isn’t a long term viable option there because 1) he’d be wasted here and 2) he doesn’t have the right attributes for that position. Like someone else said, it would be like signing Neymar and playing him as a central midfielder. Pointless.
