I too am slightly surprised most of the talk, rumour has been about attacking players. I don't know much about Alberto to be honest, Alpas I like having seen him play a few times, more of a Suarez type than any other linked with us. Mkhitaryan is much more expensive, and from what I have heard the deal more complex, again I haven't seen a great deal of him, but those who have say he is quality.
Also strongly linked with Porto winger Christian Atsu.
That all said I am certain a centre back is still on the cards, and with doubts about Skrtel/Coates we may even need 2.
Might be dependant on Kelly or Wisdom being a suitable back up.
Possible a Reina out Mignolet in also.
I also think we need a new left back for competition for Enrique.
At the moment I can't see Suarez staying, Assaidi not sure why he was bought as he has hardly had a chance.
We could have quite an interesting midfield, forward line if you add in the likes of Suso, Sterling, Coutinho and Sturridge.
Time will tell what is going on I guess.
