But it's two full seasons, he's worth way more than £90m to buy him out of a contract that long. That figure is more acceptable for a 1 year contract(but as the above poster says, Hazard to Madrid might suggest otherwise even there) with a player as highly rated as Sané with so many years ahead of him.
Also Bayern have very few options out there, even the commentary from their game last night was stating how urgent they are to replace Robben and Ribbery. They can't afford to wait 2years. Most of their other options are off the table. We should be stating what he's worth immediately and that we aren't looking to sell... £120m is quite reasonable in this market I thought. As I said look at the fees Chelsea got for players surplus to requirements in recent years, never mind a player as good as Sané who we want to keep. We are way way behind in this area and it needs to change. It's more about our lack of nous in the way things work, we might not be looking to sell at all but we should be protecting ourselves by making sure if he does go we get the highest fee possible by making the right statements.
The contract we signed him on at least appears to have been smartly done at least, we just aren't making a point of how strong our position is publicly for some reason.
