Until he tweaks his little toe and is out for another 12 weeks.
As part of my work I was chatting to an ex Liverpool star about 10 days ago. Won't name names, but let's just say he played for us in the 80s and 90s, still lives in the area, is heavily involved in media work mostly outside of Britain/Ireland, and is still well-connected to the club.
Anyway, he said to me that from what he understands, people inside the club are starting to get very annoyed at Sturridge because of his recovery patterns. The suggestion was definitely that he's taking far too long to nurse himself back to fitness and is too unwilling to play through even the slightest discomfort.
Now feel free to take this with a mountain of salt and I've no guarantee that it's gospel truth, but if it was even somewhat accurate, it's more than a little frustrating and tallies with the 'china doll' view of Sturridge that some have. It's also a bit worrying if/when he goes down with an injury again this season.
For that reason, I think the answer to the thread title is that even though he'll help a lot when fit, no, he can't be relied upon to save our season.
