Having watched a lot of the World Cup, I think Vida would be a top drawer signing for us and I hope we have/had something in place before the tournament properly got going for him. Dodgy haircut aside, he's a proper CB - mean, harsh in the tackle, reasonably good on the ball, good in the air. Little bit on the slow side but you can't have it all. I was very impressed with him at the WC and I think he'd work really well in a three man defence and would give us some added steel at the back. Hause is ready to come in at any time and has been featured heavily on our social media pages throughout pre-season so I think him and MGW will be 'promoted/pushed on' in their development and roles within the squad this season.
There's absolutely no doubt in my mind that we need to bring in another CM. We're going in to the season with Neves & Saiss - and MGW (who lets not forget we're unsure will work in a midfield two) as our options. We need some more numbers/quality there without a shadow of a doubt.
Wing back is an area of concern. I can deal with Douglas/Vinagre on the one side but we still have zero cover/competition for Doherty - German Phil will likely never play for us, plus he's injured again isn't he? We simply have to sign another RWB.
I'm the same as Johnny on the FW. It would be nice if someone absolutely top drawer came available, but we've got Raul (who deserves a chance), Jota/Cav/Costa rotating as a fluid front three, Bonatini and even Rafa Mir has found his shooting boots this pre-season, even if it's early doors. So I can see the sense in holding out in that position unless we're offered something too good to turn down.
