Yes, they are not ready yet for England which makes total sense but the talent is there. Kana is 17 and is pure class imo.Might be an unpopular opinion, but they are far too raw. They need at least 3 years of experience in a good side to be worth our attention.
On paper Anderlecht is an exciting project, but they are in a deep crisis. Young talent needs to play alongside experienced players and win most matches to develop into star players. Right now they only have potential and a club without the structure to develop them.
They should be on our radar already. We should have snapped up Tielemans for example. Still pisses me off that we missed out on him.
