AS Roma striker Edin Dzeko admits frustration over last season's Champions League defeat to Liverpool.

Roma were eliminated at the semifinal stage.

Dzeko said, “I just think we gave it away too easily there at Anfield, and made it difficult for ourselves to get back into it at the Olimpico.

“I'm not thinking about retirement at all... I've got a good few years left in me yet. But, of course yes, football can be incredibly glamorous and that is what the fans mostly see - but behind that there is a lot of things that go into it for players, some of it hard.

“Football is not so easy, not like everyone thinks. I know people often think about the money, but we all started because we love the game and we wanted to become good at it. And there is pressure and hard work that goes into achieving that."
