Play wingback as a last option over Ralls not because he is a wing back but because I also think a winger who always seemed to have a decent record of tracking back would offer more for us there than a centre midfielder who even in his prime probably isn't as quick as the "legs gone" Hoilett.
He certainly isn't the player he was of course and I also think he will be gone at the end of the season which is possibly part of why he isn't being used even as a last resort.
Season is over now, I'd like a few more youngsters thrown in and given actual time like Sang has.
