Liverpool boss Jurgen Klopp fired a warning at Manchester United and Newcastle after their 3-0 win against Leicester City.
The Reds moved within a point of the top four pair, having played one game more, with this win at the King Power stadium.
Klopp said, "Sensational first goal. Top second goal. We should have scored immediately after.
"Third goal, what a wonderful routine. Love it. Good win, super important for us.
"We have two difficult games to come. Villa are fighting for Europe. Tonight I'm really happy.
"That's the best free-kick routine we have. We should have scored three like that. Now we can take it direct or roll it both sides so it makes it more likely we score from these situations. We have to use it more often.
"We changed so many things. Now we just have to play a different rhythm."
On their Champions League rivals, he added: "I think they'd have preferred we lose tonight. I would in their shoes. I don't think it's likely but if they slip, we have to be there. Will they slip? I don't know. Will we win both games? I don't know.
"West Ham will be happy. Now David Moyes can prepare the European semi-final."
