If you don't mind one player on 8 chem you could swap the following
Lavezzi > El Shaawary
Coentrao > Constant
Moutinho > De Rossi
Ramos > Chiellini
8 chem would not do my OCD much good.

Diakite instead of UP Koscielny / Kaboul?!
I didn't realise Kaboul would go there, I thought it would mess up chem but he goes in fine.

Diakite is just asking for trouble, of all the defenders you could choose he's definitely not one them. Personally if you want a solid defence I would focus on the following
Thiago
Ramos
Benatia
Chiellini
Thiago and Ramos would be my first choice!
Almost impossible to get them together with Ibra in a 4231-2.

I'm going to give the above posted squad a try with Kaboul instead of Diakite. Work rates seems OK I think!
