Van Gaal reveals funny reason he subbed Herrera against Swansea

The United manager has explained the reasons behind all his substitutions in the game against Swansea.

United made three changes and Van Gaal has give his reason for each, but the reason for his final substitution is a little funny.

Jones was substituted at half time, while Young about 10 minutes to go,  and Herrera late on.

After the game, he said:

"Jones is injured, more or less the same injury as before. Young has played a lot of matches in a row, so he was stiff and had to be changed. It was not voluntary, I changed them because I needed to change. With Herrera, it was because I wanted to waste time, as Swansea did all
match."
