Mauricio Pochettino has been charged by the Football Association after he furiously confronted referee Mike Dean at the end of Tottenham Hotspur's defeat by Burnley on Saturday. "We made some mistakes on the pitch and I made some mistakes afterwards on the pitch".
He added: "It's not how I normally behave, maybe because I knew very well before and after the game, when we lost, that it is going to be hard to be a real contender".
"I said, for me this game is going to be key to put pressure on our opponents".
The FA are now investigating the audio recording of the exchange between Pochettino and Dean - but the PGMOL have chose to move the official away from the club's next fixture to avoid any further controversy.
Pochettino did not reveal what was said or the reason for the strength of his feelings, with the only really contentious decision appearing to be the award of a corner that led to Chris Wood's opening goal.
"I think it was a fantastic opportunity for us to be a real contender and to show we are there because we deserve it".
"But at the end, because of the emotions, everyone was nervous, sometimes we find answers, excuses, and try to justify the defeat".
It was a bitter blow for third placed Tottenham, who will be eight points off top spot if second placed Liverpool, now level on points with City, win at Manchester United on Sunday. Something stupid happens and you react.
Tottenham had been boosted by the early return of Harry Kane from an injury, but even a goal from the England striker wasn't enough to prevent a damaging loss.
"There were no big chats, we had a quick chat about and said "that's not us" and reminded them of a few things that make us what we are". "Spurs are a top side but we didn't allow them to play their usual game".
