I wouldn't put Rakitic in the same category of midfielder and we already have de Bruyne and Gundogan for that position.Kante, Rakitic, N'Zonzi?
I think Kante might be a tough one to go after unless we can persuade Chelsea that us signing him will fund their moves for Sarri and Jorginho. N'Zonzi seems like a solid option, but he's already 29.
