The manager chose not to use Young, who was on the bench, due to an injury the Englishman sustained in training.
When Jesse Lingard limped off injured in the first half against the Cherries, van Gaal chose to bring on Andreas Pereira in his place, rather than the more experienced Young. The 30-year-old has struggled for opportunities recently and would have been disappointed not to get on the pitch with Man United chasing a goal.
Van Gaal clarified the situation after the game: “In training he had a a feeling that he was not fit enough.”
It begs the question as to why Young was even on the bench if he was not fit enough to play. United seemed short of ideas in the second half at the Vitality Stadium and the introduction of players from the bench could have been the factor that helped them get a goal. Young was, essentially, simply making up the numbers on the bench, especially if van Gaal knew he could not use him.
It could be viewed as another indication of how poor and small a squad United have this season. If Young was left out of the match-day squad, there are not many players with Premier League experience who could have taken his place on the bench.
The former Aston Villa winger is a senior player in the squad and his experience could be valuable but surely a viable attacking option would have made more sense to have on the bench.
