The first three episodes of Amazon’s eagerly-anticipated ‘All or Nothing: Tottenham’ documentary were released earlier this week.And football fans have thoroughly enjoyed seeing behind-the-scenes footage of the period from when Jose Mourinho replaced Mauricio Pochettino as head coach in November 2019.Unsurprisingly, Mourinho is the undisputed star of the show. Several clips involving the 57-year-old from the new documentary have already gone viral on social media.In one clip, Mourinho calls out Dele Alli during a team meeting, calling the midfielder a “f***ing lazy” trainer.The revered Portuguese coach also expresses his concerns to chairman Daniel Levy about Alli’s approach to training.However, he also tells Levy that Sir Alex Ferguson told him to sign the England international for Manchester United.There’s also a brilliant moment where Mourinho sits down with Dele, who turned 24 in April, and tells him straight that he’ll regret failing to fulfil his potential unless he knuckles down."Maybe, inside, you are telling me to f*** off, but I have to tell you exactly what I see," Mourinho tells the midfielder."I have no doubts about your potential. I saw you do incredible things in incredible matches. But I always felt that you had ups and downs.p1eh9b0pm782f1d2k1625m1u1n8jd.jpg"There is a huge difference between a player who has consistency and a player who has moments. That is what makes the difference between a top, top player and a player with top potential."It is something to analyse yourself for you to realise why your career has been MK Dons, Tottenham, national team... bang!"Then, when you reached the top, why do you have these little ups and downs."I don't know if it is to do with your lifestyle - if in one period you were an amazing professional but in another period you felt you had become a party boy."I have no idea - only you can know that.p1eh9b10f61gci1f41ldn1snv124vf.jpg"I am 56 now and yesterday I was 20. Time flies.“One day I think you will regret it if you don't reach what you can reach."I am not expecting you to be the man of the match every game. I am not expecting you to score goals every game. I want just to tell you that you will regret it."You should demand more from yourself. It should not be me demanding more from you."Nobody else. You. You should demand more from yourself."Watch the clip in full here…

It’s incredible to see such rare footage of a manager-player meeting at a Premier League club.

Mourinho’s communication and management skills here are magnificent.

He made it clear to Dele that it’s on *him* to ensure he maximises his potential and nobody else.

It will be fascinating to see where the midfielder now flourishes under Mourinho’s management over the next couple of seasons.
