Liverpool boss Jurgen Klopp has explained hooking Alexis Mac Allister at halftime at Wolves.

The Reds were 1-0 down at the break before fighting back to win 3-1.

Klopp said: "The good thing about the first half was that it was that bad that I didn't think we could play the second half like that.

"Obviously we wanted to start completely differently, but for whatever reason it was not possible for the boys, you can see it.

"Low energy level, Macca [Mac Allister], some others as well, you could just see they struggled. We couldn't change five times at half-time, so we thought we'd change the system and one player, and give us a bit more speed up front, natural speed.

"He had some good moments in the first half but he was not disappointed to come off, more relief."
