Mount, in a similar contract situation, went for 65m after a poor season. Gallagher is coming off an absolutely excellent one. So, like, maybe? Mount had previously hit higher highs than Gallagher hit this season, though.
He's also, as SEPH said above, easily better than Palhinha and Onana who just went for 50m and 60m.
People underrate him still, which is baffling to me because if you ask any Chelsea fan he was easily our second best player last season and was absolutely brilliant.
Idk, who even knows what the market is anymore. And who knows how he'll look in a different league, in a different country! But if he had more than a year left on his contract he would be comfortably 60+.
