Chelsea manager Mauricio Pochettino has explained why he refused to shake Pep Guardiola's hand when the Blues faced Manchester City in November.
The two sides were involved in a Premier League classing after playing to an entertaining 4-4 draw at Stamford Bridge.
However, when the full-time whistle went Pochettino straight to the officials and snubbed a handshake from the Citizens boss.

Pochettino has now revealed the incident was a mistake and was due to going to confront the referee.
"No, because I was so angry with the referee, remember? That was why," Pochettino told reporters, as per Goal.
"I then apologised in my press conference after the game. Of course, it is not going to happen again. "
I was so upset with the referee and I went like an arrow to the pitch to try and fight with the referee. Big mistake and I say sorry again.
"I need to be more calm and relaxed and to show respect to the opponent. I feel really bad, but I apologise again."
Chelsea and City will clash for the second time at the Etihad on Saturday evening.
