I looked mate "all he was known to be lazy" hindsight is just that retrofitting the past. It amounts to one article and a quote. That can't really be stood up. He was a hugely regarded talent that lots of top sides wanted. You can find way more disparaging quotes about players as brilliant and KDB and Mo Salah. If one genius being down about a given young player was the red flag some make out you wouldn't sign anyone. Thankfully this crap is no longer our problem.
Sorry but that is plain bullshit from you.
As soon as the links got concrete, there was certified quotes from his former coach if not from multiple coaches who put his determination under question. I think it was also listed as reason why he was dropped from previous club.
There were neve-ever-ever anything even close to such legit quotes about players like van de Ven, Vicario, Udogie or basically anyone at all, that would have been brought up.
So red flags were there BEFORE day one and it cannot be even argued. Go back to beginning of the same thread. I remember this summer well and I had little bit of suspicion about him. As I did with Aurier when he was signed. And really no others. Both turned out to be flops, though Ndombelly McFatFuck much more so.
