This is all pie in the sky and just my opinion.
I don't see Suarez as city/Pep player. I also fail to see why he would leave Barcelona at this time? It makes no odds unless he's fell out.
Along with Neymar he is the foundation that Barcelona will build around. Neymar is a different type of personality but another one that I just can't see them selling.
If said rumour is true and we are after one of their players then it's Messi. He's had the twilight of his career with them, and may last another 2/3 years at the top of his game. They can still demand a world record fee and probably get it. He also adores Pep. That one makes more sense than any of them.
However I think it's bollocks and there is not prayer for any if them in my opinion.
