If Juventus and Spurs do come to an agreement, and Bernardeschi heads to north London, it will be interesting to see where he fits in, and how Mourinho chooses to use a player with a very different skill set to Ndombele.
The Italian is a gifted footballer. Even his harshest detractors would not doubt that.
He is technically proficient, a superb crosser of the ball, and an accomplished set-piece taker when on top form. And he is versatile enough to play in various attacking roles.
But there are doubts. Bernardeschi is not yet truly established as an elite player, despite three years at Juventus.
He is 26 years old now, approaching what should be his best years, but for much of his time in Turin he has divided opinion.
Last term, in particular, proved a difficult one for the Italy international. He started 19 Serie A games – making a further ten appearances from the bench – but only managed one goal and one assist.
It was, in truth, underwhelming, and the Bianconeri fans weren’t shy about voicing their opinions.
There was vocal criticism, suggestions that the former Fiorentina man should be nowhere near the first team.
“He is a boy who has the defect of not having a consistency of performance,” Maurizio Sarri, Juventus manager last season, said.
“People, I don’t know why, always expect a lot from him. He is a hyper criticised player, much more criticised than what he deserves, then when he has good times he is not noticed.
“In my opinion, the criticism is too strong towards Bernardeschi. He is a strong player, who if he finds a long period of confidence can solve the small problem of consistency and can finally reach his potential, which is of a high level from a technical point of view, but also from a physical point of view.
“He is a boy who has acceleration and endurance.”
For all of Sarri’s encouragement, it seems others at the club are less convinced. It is hardly surprising, then, that new boss Andrea Pirlo appears to be willing to move Bernardeschi on.
If he joins Tottenham, he will hope to reignite his career, though the challenge would be no easier.

He has played primarily as a right winger or attacking midfielder for Juventus, which would mean competing with the likes of Lucas Moura, Dele Alli, Erik Lamela, and Giovani Lo Celso for a place in Mourinho’s starting XI.
He would certainly provide more depth in that area, and has qualities that would add another element to this Spurs side in the final third. But it is hardly a prospective signing to inspire fans.
The question Tottenham must ask is whether or not the player truly improves the team. Sarri may have believed in him, but it will feel like a risk if Spurs choose to put their faith in Bernardeschi.
