Seemed to me like he just wanted to give player's game time and it was pre-planned, bit risky with the game still in the balance though. Blackett for Shaw was forced. I'd imagine it was pre-planned that Falcao would only play 75 mins, surprised to see Wilson come on though, thought maybe Fletch would come on to protect the lead. Perhaps pre-planned to give Fellaini some game time too, taking Valencia off was another surprise though.
