This blocking minutes for Gordon nonsense is utter nonsense. Also worth noting that it's only under king Rafael that Gordon has finally started showing what he'd capable of more consistently.
If you look at his appearances this season though he's only really started due to someone being out. With DCL out, Richy went up top so Gordon came in with Gray and Townsend. Same when Richy was out with Rondon up top.
When DCL, Richy, Gray & Townsend have been on the pitch together (4 games) he's only got 1 minute of play time. Even after that he was having Iwobi picked over him till United game.
It's a valid concern that he's going to end up 3rd/4th choice when everyone is available.
