Ange Postecoglou has been captured unleashing a furious rant at his Tottenham Hotspur players during their English Premier League clash with Chelsea. 

The Greek-Aussie is often known for his cool, calm and composed persona as well as a strong attacking football philosophy. 

Although, those who remember his time at Celtic will recall that he has never been afraid to make his feelings known from the touchline if required - especially when his team aren't matching the high demands he sets. 

He was once heard screaming at Celtic's Stephen Welsh during a cup tie against Raith Rovers, when he needlessly passed the ball straight back to goalkeeper, Joe Hart.

And a similar theme seems to have emerged this evening. With the Thursday night match at Stamford Bridge televised on Sky Sports, cameras panned to a red in the face, Postecoglou, who vented to his underperforming Spurs stars and angrily stated, "stop passing backwards."

Co-commentator Gary Neville highlighted the situation while the scoreline sat 1-0 in Chelsea’s favour, and said: "He's having a right go at Sarr and he's having a right go at Romero.

"Ange Postecoglou has snapped."

Spurs have now lost their last three league games, with their hopes of securing Champions League football for next season being dashed.  

In his post-match press conference, which lasted less than three minutes, a fed-up Postecoglou commented: "It wasn't a great night. We didn't have the mindset that I expect us to have, so that's on me, I've got to take responsibility for that.

"Ultimately I'm the one that's putting them out there and preparing them for it. We were so far off it I've got to look at myself and see how I'm preparing this team for it."
