Liverpool coach McMahon heaps praise on Amoo
"We keep saying to David he needs to be on the score sheet more often and he did well tonight," McMahon told Liverpoolfc.tv.
"Me and Antonio (Gomez Perez) lost a bet with him because we said if he scored tonight then Antonio would pay for the next meal we have out as a squad, so we are a little bit disappointed!
"I'm happy for David as he is always looking threatening and looking to score goals. It's always nice to be threatening whenever we go forward.
"We have a lot of good pace in the side and players that can cause problems for defenders.
"We played a lot of good stuff but we had a little bit of anger at the end because we conceded a goal. We switched off near the end when we conceded the penalty but overall we are really pleased."
