Lucas Leiva is delighted with his new deal at Liverpool.

The Brazil midfielder penned new terms earlier this season.

Lucas told the Observer: "The new contract will cover the best years of my career and I am glad they will be at Liverpool because I have worked hard to establish myself here. I really believe the club will be back to where it belongs soon, fighting for titles and Champions League qualification, and we can do it no matter how difficult it has been this season.

"If I didn't have that belief I may not have signed. This club has given me everything as a player and a person. I want to repay that and help take the club back."
