I'm reading this 'promised champions' a lot. Firstly, you don't promise in football, because there are zero guarantees.
'Champions' in the Italian sense does not particularly mean Agüero, Neymar and Tevez, for example. Those come under the almost equally bandied about phrase 'top player'. For instance in some sources the trio of Beck, Mascherano and Bastos were classed as three champions. I'm pretty sure that Marotta will also claim Vidal, Vucinic, +1 (also maybe Pirlo) as 'champions'.
For those who expected three world class players, well...
So far I'll go along with it being a good mercato, although we seem to be stocking up massively on attacking players and it wouldn't surprise me to see Marotta make a 'dream' move for his 'top player' Rossi. He hasn't sign a real headline grabber yet, and I hope he doesn't if we bring in Vucinic, we need a LW and DC next.
