Yeah his injuries have been terrible the last 2 seasons, though it wasn't a couple of long injuries back-to-back, with no playing time in-between. He did his ACL soon after moving to Fiorentina, returned from it, and was the Serie A's leading scorer last season (the stats quoted above) - until he did his ACL again (or got some other knee ligament injury). Then he returned for the final 3 games of the season, and scored in 2 of those 3 games. Wasn't picked for Italy and was miffed (can't blame the manager there, surely).
This is the sort of risky move that could be considered if the price was right. As a backup to Sturridge, he should be getting a bit more rest and not needed to play full games back-to-back. I don't think he'll be cheap though, so this will more likely end up as an unviable option.
