The wages are not as high as quoted it is not 200K quoted. The Basic is about 120K with 80K in bonuses at Lyon he decided to reduce his wages to 80K and forgo the bonuses in his contract. I am sure if PSG miss out on Pogba they will consider an approach if he is willing to cut his wages again. For Ndombele I think it is more about the status of the next club.
£80k pw is certainly an easier sell than £200k pw : but outside the very top clubs in europe that's still a high wage which a club would expect to pay only to a midfielder who was highly regarded and a first team member...... and even a number of those players might be paid more like 50% of the £80k pw.
I suspect we'd still find we needed to subsidise his wages to help him move on.
