Having got rid of one striker and only brought in one I don't see Chelsea selling in this window, to us or anyone else. Torres may not be up to the level most expect of him in blue, but he's far better than your average back up if that is the role you think he should have behind Ba.
But, while its a while between now and the end of the season, with plenty of opportunity for the blond Spaniard to change opinions, I think the fate of Torres maybe directly tied with the fate of Rafa. If Rafa is to survive beyond being an interim manager it will be more than likely because he got Torres firing on all cylinders. But if Torres continues to fail to impress, then think Rafa will be replaced, and the new man will have much more leeway in letting him go.
As for him coming back to LFC, not against it or for it, it all depends on how much it would cost. He still has value that is for sure, it’s just nowhere what his sale price was 24 months ago.
