Depends who our other options are, I guess. Right now you'd expect the front 3 to be Suarez, Sturridge, and Coutinho. Possible competition from Borini, Aspas, Alberto, Downing.
So basically, hard to see where they get in the 'first team', but no reason at least one of them can't force their way on to the bench as a regular back up - the alternatives are fairly underwhelming really. I'd keep them here til xmas and if it's needed send one on loan for 6 months then.
