Former Roma midfielder Alberto Aquilani is determined to prove himself value for money at Liverpool.

"I know Liverpool have spent millions on signing me but I'm here to prove I'm worth it." the 25-year-old told liverpoolfc.tv.

The former Roma man is also looking forward to playing in the Premier League, which he has so far enjoyed watching from afar.

"It's very good fun watching it, mostly because the matches are never over, and even if you are leading by two or three goals, you still keep attacking," he said.

"I can't say if it is the best football in Europe, but for sure it's the most spectacular, dynamic and challenging.

"And the stadiums, every time I played there, they are beautiful and all have a terrific atmosphere."

He added: "There are champions at this club, such as Fernando Torres and Steven Gerrard, who can make the difference at any moment and inspire the team.

"I'm thrilled to play alongside them also because I'm sure they will be able to improve my game."
