Terry Yorath
He will no doubt improve with game time, just like Davies did at LCB.
The one challenge with Forster could be his body and age with games coming thick and fast. He hasn't got Davies's scenario where he's only ever played 20 games in the position he's been asked to fill. Forster has played hundreds of games and is a specialist at it.
The only other area might be his feet. I don't overly remember him being too tippy tappy with the passing like some of the modern keepers.
