Sunderland boss Steve Bruce admits he's scratching around for strikers.
Connor Wickham's knee injury is the latest blow to Bruce's planning.
Bruce said: "I watched England last weekend and our two centre-forwards this time last year were Welbeck and Bent, so to lose that talent and replace them is going to take some time and some doing, but gradually we are getting there.
"Connor was starting to grow into it, certainly Nicklas has benefited from coming to Sunderland - he has got five in five for Denmark since he has come here - and Ryan will score goals but physically the kid has still got a long way to go. He took his top off the other day and he was still like a little boy, bless him."
