Then no - one would risk at buying players for higher prices. Because they all can flop lol.No offence but the amount of times I've seen this kind of statement from people about players and then they turn out to be wrong..
No player is guaranteed to not be a flop at any one club. Even uber talented players, there's so many reasons a transfer can not work out. And even City, PSG etc would baulk at spending 80 million on a young cb.
Of course you cannot say 100%, but I’m 90% sure he’ll be world class in years to come. I watched him play for 100 matches. Top rated young CB in the world.
