I really don't think Borini will play anywhere but as a striker if we sign him. Rodgers played him as a number 9 at swansea, and always played with wingers. Borini just isn't the type of player rodgers has used so far out wide.
See, I thought Rodgers would use Suarez out wide and play Carroll through the middle, but I remember saying the big thing Rodgers will have at Liverpool that he could never properly replicate at Swansea, is that Suarez gives him a genuine option to use a "false 9", something he's never had elsewhere. Given how he loves Barcelona I think there's always going to be the attraction to trying to replicate that with someone like Suarez through the centre.
Suarez also plays a similar role for Uruguay, with them using Cavani, a more traditional striker, in a wider and deeper role.
Suarez could play wherever along the front though, let's be fair.
