Everton fan here. Think we are all accepting he will leave in the summer along with Onana.
What I will say is that you dont want to be missing out on him. He deserves better than Utd and Spurs and when he does go I'd prefer to see him at City or Real Madrid.
The lad for me is better than Stones when he was at Everton. Im not saying he will be better than Stones in the future but at this point in his career, he's a superior defender than Stones at the same point. He reads the game unbelievably for his age. He is deceptively fast, tall, very strong, both footed and enjoys defending. But like Stones, is so calm on the ball and is technically excellent. He will put it in row z when need be too.
Providing he stays healthy and carries on progressing at the same rate he is, he will become one of the best imo.
