Heitinga's better than Yobo, that's all there is too it really. And neither of them have picked up injuries, Yakubu has, and on top of coming back late, didn't deserve to be selected. He's competing with two players, and Beckford and Saha earned there 'chance' during pre-season.
He may well be a gonner, but he hasn't left yet and Moyes has said he'll use him, but like everything else, he'd got to earn his place in the side. As of now, he hasn't done that. Did you really expect him to be on the bench? I didn't. It'd be a slap in the face of Beckford
