Take a look at the record of Danny Ings. Benteke's too. To be honest, we have three of the more injury prone strikers in the PL. We could carry Sturridge if the others were fit but they're just as unlikely to be available. We need to buy at least one top striker in January - and then let either Benteke or Ings go in the Summer. I'd go back for Lacazette, if he's still available. We are too vulnerable with these three. I do think Sturridge is the classiest in the league, when he's fit. I don't want to sell him under any circumstances. Perhaps in two years it will look very different but for now I'd keep him.
