Manchester United boss Louis van Gaal explained his triple substitution for victory over Champions League opponents Wolfsburg.

Antonio Valencia, Bastian Schweinsteiger and Memphis were all taken off during the 2-1 win.

Van Gaal stated: "No, I think it was tactical because I wanted to prevent crosses from that side and Antonio let them cross.

"Also, I saw that at that side they could be more effective on that side. Schweinsteiger, he was tired I thought and that was the reason, because he also gave balls away and Schweinsteiger is normally the best possession player, so that is the reason I changed him. The same for Memphis."
