Weird thing is Hansern that I wasn't a huge fan of Cresswell's at Ipswich and still remain unconvinced by him. He is very good with set-pieces and pushing forward but is IMO not much better defensively than Moreno. Your comparison to Robertson is apt as they are very similar players i.e. I don't think Robertson will help our defensive lapses although he's very good going forward. I haven't seen enough of Kieran Tierney of Celtic but have been very impressed when I have seen him AND Celtic supporting friends of mine who have previously "flagged-up" Wanyama, Van Dijk, Forster etc think Tierney is the "real deal".
