James Milner says Liverpool must deliver a trophy before they are worthy of the description "best team in the world" after a lavish tribute from Sergio Conceicao, the Porto coach.

The gushing praise was accepted with a heavy dose of scepticism by Milner and his manager, Jurgen Klopp, who hinted the premature adulation might have an ulterior motive ahead of the second leg of the Champions League quarter- final, which Liverpool lead 2-0.

"That’s a nice compliment, and you get those compliments by playing good football over a sustained period of time so we can take that as a compliment," said Milner.

"But to be that, I think you have to win trophies, and that’s something we haven’t done yet and something we’re trying to do this season.

"There are a lot of good teams left in the Champions League and it’s down to us to prove that and go and win these games and, hopefully, win at least one trophy this season."
