Gerrard is getting on a bit and was rubbish last season. Carragher is well past it. Torres is increasingly injury prone.
There's no guarantee those three plus Mascherano won't be leaving in the next few weeks anyway. I don't see much in the way of young talent maturing and there certainly won't be much of that in the next decade or so either after the clown's men got involved.
It's unlikely Hodgson will get much in the way of funds to build a squad with in the short term.
