Liverpool boss Rafa Benitez admits he has concerns over Lucas Leiva and Javier Mascherano's Beijing Olympics ambitions.

He told liverpoolfc.tv: "It is two different things. Lucas is in the age range so we cannot say anything if he wants to play in the Olympics. It could be good for him. We need to analyse the position with Mascherano. I was talking with him today and we need to consider everything and then decide. We have time and maybe in a week's time we will decide."
