100% yes, no doubt in my mind on this one. We will most likely be playing 4 at the back next year which means we need at least 2 right back options. Given that Elmo is more of a winger that leaves us with 0 out and out rightbacks (McShane is a CB in my view) Rosenior has the ability to be first choice RB, but has also shown this season he has the mentality to be a back up player and still give everything when he does get a chance. If we were to try and replace him it would cost more than he'd want in wages and no doubt a transfer fee too, with this in mind, an expected limited budget for transfers and far more important areas to sort out - left back, cm, strikers, goalkeeper, it really would be foolish to let him go.
