Where is there any evidence that Ndiaye is motivated by the dollar? If he was then he would have asked for a transfer last summer and in January when clubs started bidding for him. Billy left other clubs to join us as he wanted to play for his boyhood club. Was he greedy when he left Scunthorpe, or is that different because it's us. Ndiaye has been a great player for us and if he wants to fulfill his dream of playing for his boyhood club then that doesn't make him a greedy mercenary. John Lundstram was a greedy mercenary. Iliman Ndiaye, no.
Players get sold. Players have ambitions and some ambitions can't be fulfilled staying "loyal" at a poorly run, broke Championship club that pays peanuts and will likely be back down in the Championship come May.
If we get a good price for him and Hecky gets all of the fee to use then so be it. One disadvantage we had last time in the top flight is that we didn't have a Grealish or a player we could sell for big bucks to help finance our following summer. This summer selling Ndiaye and Berge could potentially generate £25-30mil, which would give Hecky a significantly better chance in the transfer market, or in rebuilding a team for promotion after this season, which is better than letting them go for free in the summer where we'd then be trying to replace them with little to no money, as our club seems to be good at making the Premier League windfall dissappear quicker than it arrives.
I'm not saying I want Ndiaye to go, but we might have no choice.
