Chelsea manager, Thomas Tuchel, reportedly told his FC Porto counterpart Sergio Conceicao to “F*** off”, after their Champions League quarter-final second leg.
Tuchel also clashed with Porto captain Pepe, as he celebrated their qualification for the semi-final on a 2-1 aggregate.
Mehdi Taremi’s 93rd minute goal was not enough for the Portuguese side who lost 2-0 at home last week.
TV footage then showed Tuchel barely stopping to exchange handshakes with a stony-faced Conceicao at full-time, despite greeting his coaching staff.
Conceicao shouted angrily after the Blues boss, with the pair having previously clashed during the game when Porto were denied a penalty.
Speaking in his post-match press conference, Conceicao said: “I was telling the referee that the fourth referee heard those insults from Tuchel. That’s all.
“I don’t know why he reacted the way he did. I didn’t say anything to him during the game.”
Tuchel, on his part, said: “It was just a little argument with me and their coach, and everybody was following me suddenly.
“No harm done.”
