Roy Keane admitted he was shocked by Tottenham's 'All or Nothing' documentary as he claimed it revealed the Spurs dressing room was full of 'children' and Harry Kane's inept leadership skills.
Spurs were chosen by Amazon Prime to feature on the fly-on-the-wall documentary series unveiling the behind-the-scenes culture at the club during the 2019-20 season, which saw the north Londoners sack Mauricio Pochettino for Jose Mourinho.
And former Manchester United Keane took aim at several Spurs players after seeing the Amazon show, including Dele Alli and Eric Dier, for showing a lack of emotion in the dressing room.
'Spurs must be a hard job,' Keane told Sky Sports pundit Micah Richards in their 'Driving Home for Christmas' series. 'Imagine the culture at Spurs.
'Have you seen that documentary? When I watched that documentary - and I know it can get edited and all that - I was shocked (at) what was going on at the club.
'Even the players in the dressing room, the medical room - everyone was on their phones. They showed a couple of players falling out, maybe it was Alli and Dier, but they were arguing like children.
'They were going "oh you need to do your job". There was no aggression! They were like actors with no emotion behind it.'
Keane also criticised the pre-match team talks by Tottenham striker Kane - who is vice-captain to Hugo Lloris at the north London club - with the Sky Sports pundit claiming the England national team skipper needs to 'liven up a bit'.
'Harry Kane was doing a talk before the games,' Keane added. 'Oh my God Harry, you need to liven up man.
'First of all, if you're going to have a speech before every game, players are going to get bored of it. Why (do) you think you need speeches before matches?
'And you know when people were having huddles before the match and there's like 600 people in it? It loses what it's about.
'The bus driver was in it, the chef (as well). I'd be like "You, get out of this circle of whatever we're doing."'
Former Republic of Ireland captain Keane has been highly critical of Spurs - who recently hired Antonio Conte as manager - in recent seasons while on Sky Sports punditry duty.
In April of this year, when manager Mourinho was under pressure and facing the sack which he received later that month, Keane claimed that Spurs have been 'soft' for the last 40 years and will continue to have that side to them.
'There is a softness in this Spurs team,' he said on punditry duty at the time. 'Yea, they got to the Champions League final (in 2019) but they were lucky to get to that final.
'Also, getting to the final is like being top of the league in November. They got to the final but they got beaten in the final.
'And when Mourinho leaves, there will still be softness to this Spurs team. That's down to the players.'
