It is really difficult to understand Antonio Conte about this transfer. Because they should be looking for capable wingers who can score and make assists at the same time. For example, they had Gareth Bale in the last season and he performed very well. He got 11 goals and 3 assists in the English Premier League. And now, he is one of the biggest candidates to leave Real Madrid and he can be transferred for free now. As he is 32 years old, I think that he can still be very helpful for Tottenham. Therefore, I'd go for him instead of Traore.
Or if they really want to sign a younger player, than they should be looking for talented wingers.
I believe if they could get Bale then they would have, but Traore have been in the premier league and he is not as expensive when you look at the salary differences. Bale is great and all but he has a very high salary so that is the biggest difference. Which is the main reason why they are probably looking at him. Plus Traore is 25 years old and that is a big difference to be fair, if a player is 7 years younger than you could get that player and then make them play a bit better by fitting them into your strategy as well.
So, this is not a horrible transfer choice to be fair, yeah I would agree that if you could get Bale for free and get him to accept a very low salary then you would prefer that, but if not then I would say that Traore with cheaper salary and 7 years younger looks like a better deal to get done, you can get more out of him.
