Benatia a big yes if he is available for a good price!
Lukaku I dont know - He is a player of a big name but has always failed making that next step! I`d take him for a reasonable fee and try using him as a target man we should use his strength and could allow us to quickly go forward with Bonucci`s long balls as he is likely to beat his man in a strength battle...
Lukaku is the kind of guy that could become the best box striker in the world (same goes for Balotelli) but could also be quite average!
More creative yes, better no. Perreyra is better than Vasquiz and Marchisio is better than Pirlo in hes current state.
Pereyra is not better than Vazquez.... He is faster but put this aside Vazquez is an assisting machine! I like Pereyra a lot and think he is an excellent sub to have but to say he is better than Vazquez is simply not true!
As for Marchisio or should I say Ghostisio... He is not a better player than Pirlo but Pirlo is also not better than him! They are different kind of players with one is more a box to box kind of player and the other is a pure deep lying playmaker!
If you search for creativity and organizer then Pirlo is surely the better player he could really be part of the solution to solve our lack of chemistry!
If you already have creativity and you look for a player who can attack and defend well - be a good team player then Marchisio is definitely the better player!
Seeing our team play we surely need creativity and organization as a blind man could see we desperately need it! therefore the pairing of Pirlo Vazquez would be much better for us than Marchisio Pereyra!
If we would have been as creative as Barcelona I probably would have claimed the other way around!
