It makes no sense to sell Sturridge now. His value is rock bottom right now and anybody that would be interested in him won't be able to afford his wages meaning we'd be paying him off, wiping out any fee we'd receive.
Ignoring the financial side of things, I'd still not sell him. As I said above, he's never had a great injury record but this last 18 months have been extreme. You'd hope (touch wood) that long term he'd be available 60+% of games and I'd rather have a world class striker for some of the time than a good striker all the time. We can't be relying on him though. We've got to get the best possible striker we can get and see Sturridge as a bonus when he's available. I suspect that was the thinking with Benteke but whether he's the answer remains to be seen. Like when he signed, I've no problem with his ability but you're still left wondering how and where he fits in.
