Nothing accidental about that. LVG said many times that he kept a small squad deliberately in order to give chances to young players. So when we had injuries, he gave chances to Rashford who played brilliantly and then LVG kept playing him.
LVG could have easily kept Hernandez, Nani, Rafael and co and so the likes of Rashford, Fosu-Mensah, CBJ, Lingard wouldn't get any chance to play for us.
So, I give credit to him for playing the young players, for improving Valencia, Fellaini, Young and Smalling, and for signing Martial, Blind, Shaw, Herrera among others. And for making the double over Scousers in both years, for doing well in big matches, and for winning the FA Cup.
In the end LVG undoubtedly failed and he didn't lay much foundation, but there were plenty of positives from his reign. Just that there were more negatives. On comparison, Moyes' only positives were signing Mata and Fellaini, and playing Januzaj.
