Realistically I think we will end up with Cavani plus one of either Eriksen or Isco. The problem for me is wingers. There is a lack of world class wide men on the market and any that are up for sale, like Bale, will cost in excess of £40million. Reus would be difficult but seeing as how Dortmund are likely to sign Dzeko, we may have some leverage.
We currently have the best back 5 in the premier league in; Hart, Zabaleta, Kompany, Nastasic and Clichy. We will only need to strengthen the defence if Lescot, Toure and Kolarov leave (which looks likely).
I think it will have been an exceptionally good summer if we come out of it with Cavani, Isco/Eriksen and Reus (and a back up versatile defender). 3 world class players. Quality not Quantity. If we can find buyers for Dzeko, Kolarov, and Lescott that would be great. K.Toure, Bridge and Cruz are all leaving as well. Sadly I think we will be unable to rid ourselves from Sinclair, Maicon and Garcia so we will be stuck with them.
