but i'm saying something else, i'm saying that this player alone is not enough to get a team back on its feet that has been shaky all season
according to me of course

I agree with you, that's why every team shouldn't just rely on certain players to get back to their best. Juventus didn't do well last season even though they qualified for the Champions League, but it wasn't the result they hoped for as they were desperate to win the title.
Di Maria and Pogba will be mainstays this season at Juventus, it's good that they are expected to contribute to the team and improve team performance. However, I'm sure other teams will also try to be the best and both fight for the title in the 2022/2023 season.
