Based on what, they don’t have to sell him, they aren’t cash poor, they want to keep him. No reason they would expect to get less than 60-65m, we know we have been quoted way more, even if it was just bluff. Whilst Neves may be an upgrade on mctominay you can not play him with our current midfield. So we would need a hard working box to box player with him. So add on a minimum 25-35m for someone average like tielemans
They'll likely ask for something in the ball park of 80m for him, but that would be lowered with negotiations. If you're selling anything always start with a price a fair bit over its actually valuation to ensure room for negotiations and to still make a reasonable profit.
Barca were asking for €100m for FDJ, we've managed to get the club to agree to at least 20m less for a superior player.
I think a midfield of Fred, Neves and Eriksen could work very well most games personally. It's not idea sure, but again.. if this deal does fall through I think we still need to find another player.
If we fail to get FDJ our options are: McFred, Eriksen, Bruno, Donny, Garner, Iqbal and Savage.
It makes for grim reading. Even with an improved coached and being slightly better drilled (it'll take time) that midfield is lacking in depth in terms of quality and quantity.
