I don't personally think Holgate is all that at the minute really. He's not big or strong enough to play centre half, he's no right back, he's okay at right centre of a back three but we've hardly seen him there to be honest.
If the lad was ever going to push on it was while Coleman and Mori were injured and with two ageing centre backs needing to be rested. He's not done enough so far at right back nor centre half to suggest he should be playing more often.
Granted he's young and will hopefully improve but I'm not as enthused about him as some of the other kids coming through.
