He's fine as a back up player. He's versatility and willing to give 100% whenever called upon, even if that means not playing every week. You need people like that in your squad. If he plays every week at right back then eventually we're gonna see mistakes from him that cost us, the one against Arsenal being a prime example. Further forward he can still be effective, just not often enough to be playing there week in week out anymore, unfortunately Hopefully we bring in a new right back and winger next season so he can be used more sparingly. Don't see any point in selling him, we'd not get that much and he's a good player.
