Completely disagree. Nasri and Navas proved time and again last season that they wearnt up for the job, paticularly the latter who didnt even contribute a goal in 35 games. De Bruyne is a huge upgrade on both of them
Personally I would like to see KDB brought in with Navas and Nasri being shown the door. Would then have a nice balance with proven stars, SIlva, De Bruyne and Strerling plus some promising youngsters like Lopes, Roberts, Garcia and Barker.
I'd have no problem with buying him if one of Navas/Nasri left, but we all know neither will leave.
