Gareth Bale can really cost Tottenham much higher than Adama Traore in terms of wages. But I'm still not sure about whether bringing Traore would still be a good choice. Because in this case, Antonio Conte will have a big responsibility to help him improve his performance a lot. Because his current level is definitely not enough to be able to play and be productive for a top team. If Conte helps him improve himself and reach a much better level compared to now, it would be really great. But there is no guarantee for this to happen.
I second that, personally I do not like Adama Traore, I think he is very unproductive as an attacker with no goals and assist in a pretty long while, but then, Bale isn't even a better choice, Bale is very well past his best as a player and he really can't produce too much at the top level anymore. What I think Spurs should do is put their hands deep into their pockets and bring out money to purchase a very good, quality player, if they want to compete for titles, then they must have to spend money, it's not just all about hiring and firing coaches, they must be very tactical in signing their next crop of players if they want to win trophies.
Of course, you've got a point there. Bale is not enough for Tottenham anymore. If he was having his prime now, then he would be a great choice for Tottenham. But he had his prime at Real Madrid and he is an inconsistent player now. Maybe he won't even be able to perform the same at Tottenham like he did before. At this point, Tottenham should start searching for a top winger or a promising one. But if I were in Tottenham's place, I wouldn't refrain from spending a lot of money to build a much more solid team.
