United face a trip to the Emirates Stadium on the Saturday after the international break, with LvG struggling with the vast number of injuries in his squad.
While he’s revealed that he has players fit enough to feature for 20 minutes against the Gunners, he has said he can’t name a full bench of half fit players for the Premier League game.
“They could sit on the bench because they can play 20 minutes but I cannot put a lot of players who are not 100 per cent fit on the bench,” said the Dutchman.
“You saw what happened with [Paddy] McNair [getting cramp against Crystal Palace] because the rhythm of the game is very high in the Premier League.”
United have several players who are classed touch and go for the game against Arsenal with Radamel Falcao, Phil Jones, Jonny Evans and Rafael among the players thought to be battling to be fit in time for the game.
The obvious reason van Gaal can’t name a full bench of partially fit players is because it’s impossible for him to predict when he’s going to have to make substitutions during the game.
In an ideal world, United would be able to bring players on safely in the second half while ahead during the game, but there’s no guarantee of that happening.
Van Gaal needs fully fit and fresh options to be ready for the possibility of bad injuries during the game or if he needs to change things at half time to try and counter positive tactics from Arsene Wenger’s side.
