I'm trying to be as realistic as possible and not naive about this.
If it is true, its dead on and it is a "shock"
Then I would think either/or:
Tim Cahill.
Leighton Baines.
Joey Barton.
Michael Owen.
(Or any other player from a rival club, to me that would be a "shock.")
Either that or some 30 year old+ player.
Whilst I would welcome Aguero, I dont think it would be the sort of shock as those mentioned above. Aguero is very good friends with Maxi and we dont know if Maxi is off in the summer or staying put, so if it is a possibility, I would reckon it rests on this.
However would it really be a good signing? We have our two in Suarez and Carroll, if we need another it would be for depth in that area (Don't forget we have Kuyt)and I doubt very much Aguero would want to sit on the bench for those 2or3.
We need to strengthen the squad and in other areas, rather than just up front now.
Also look at Pacheco I still think he is and will be a big part for us next season (Just look at what Dalglish is doing now) Spearing went on loan to Leicester did he not? Come back and started getting himself a repuation with us, I see a simular thing happening with Pacheco myself, so do we really need more forwards?
We need those tricky, skillful, creative wingers, cover at CB, maybe a LB and maybe 1 or 2 creative midfielders, who can link passes to our forwards like Alonso did.
Charlie Adam or Aqualiani back? or both?
Very interesting times ahead!
