#2 Danny Welbeck (Arsenal)

Arsenal's forward Danny Welbeck has been a shadow of the person that he was at Manchester United. Along with Sturridge, he was deemed as a long-time wing option for the national team until things went south.
Welbeck's injury is one of the causes for his poor form and comebacks are always tough. It is almost sure that Arsenal won't be renewing his contract this summer. Still, Welbeck's age is on his side and many teams would love to have him in their arsenal.
A move back to Manchester would not be a bad one for him and for the team. Manchester United don't need potentials at the moment, they need sure talents and Welbeck fits that category. He can provide an alternative to Alexis Sanchez if he leaves and can cover all positions in the forward line.
If not Manchester, then there are other clubs too who might need a winger. Borussia Dortmund is one, having lost Pulisic already. There is fellow English team Tottenham Hotspur and also Juventus, where Dybala and Douglas Costa both seem on the way out.
There is no shame if he goes to mid-table clubs like Sevilla, Valencia, Leicester, Wolves, etc. All of them would be blessed to have his talent on the wings, for free.
