Of Course he has an attachment mate, Muller has been linked to City a few times as wellmate, City need a LB and Alaba is one of the best in the world, especially going forward he is extremely likely to follow
We need a CB. The way Kompany has been in recent years with injury we nearly need weekly cover for him. Otamendi is a great player and I have faith in him to get better - just needs a solid CB partner which Kompany is but needs to be there.
I like the attacking threat we get from Kolarov/Clichy so we're not crying our at LB but an upgrade would certainly be handy.
To be honest I would just like us to fix up our defense and then keep the same team for awhile. Although Toure/Silva are starting to get on we have a brilliant assist replacement in KDB. Replace Toure with Pogba (I wish) and we've got a team that can win year in and year out. Iheanacho is the future of our forward line, stoked to see him come on the way he is. You've got guys like Nasri and Navas that aren't getting regular gametime that I feel will play well in the Pep style of play.
The main point I'm trying to make, we don't need to strip the side and start again. We've got the nucleus, just trim a little fat and we'll we sweet.
