Even next summer we would get £70-80m for him and more clubs would fancy him for that. Keep him, play him and try and get a new contract signed and if not, sell next summer.
We could even get more.
In 2016, the record fee for a player moving with 12 months left on their contract was €40m.
2017, €66m for Sanchez.
2018, €100m for Ronaldo.
2019, it's €100m + €30m in bonuses for Hazard.
Leroy could easily go for £80m/€90m next summer with the way prices are rising, and the way people are paying these days. If he has a good season here, followed by a standout Euro 2020 then he could go for Hazard money.
