Adama has improved loads this season and has quite a few goals and assists this season thanks for being managed well at Middlesborough.
Consider what Sane has brought to us these last 2 games, basically nothing, yes we won the league but you shouldn't be so bad that you literally stand still with the ball and let the other player just take it from you (he actually did that last game and wasn't thinking).
Adama under Pep could go up even another level, and he is still young. He can push Sane to his potential as well since Sane feels no threat to his position.
Adama can also play on either wing, Leon Bailey will be the obvious choice that City may want, but the bold choice for a bigger potential player is Adama Traore. He can be a top 3 player under the right manager, nobody runs with the ball like him, not even Messi anymore.
