This is the reason I want Nani. He's not just pace. He's proven he can play in a possession system before. He's not a one-hit wonder in a counter-attacking team.
The reason I think he can play in a possession system is because firstly, he does have great ball control and dribbling. But most importantly, he can use both feet. When you get into a tight area you have to present the defender with 2 options, not just one. Krasic had only 1 option. Push it with his right foot, to the right side.
This is why I'm so hesitant on Cerci. Firstly, his big season is in a counter-attack team with no defensive responsibilities, but also, he does not have an impressive weak foot.
Nani can push it right but feint and bring it back to his left and still be able to deliver a cross or shot. In terms of actual ability and talent, there will be few if any options that will present themselves at a price that Nani comes at. Is he a risk? Yes. Is it a worthy risk? At 10-12M, absolutely.
