Mateo Kovacic insists there is no bad blood in the Chelsea dressing room following Antonio Rudiger’s clash with Kepa Arrizabalaga.
The pair came to blows in training on Sunday following the Blues’ shock 5-2 defeat at the hands of West Brom.
Tempers flared which eventually saw Thomas Tuchel send Rudiger from training to cool off.
The Chelsea boss called on his side not to lose their head following their first defeat during his tenure.
And Kovacic maintains that the training scuffle will not linger over the group.
He said: “It’s not a big deal. It is just competition in the dressing room. We spoke about it, all cleared, all done. We are a strong group.
“These things happen in a family and strong groups. So we will accept it, we will leave it behind and we are all focused for the game tomorrow.”
Chelsea take on Porto in the last eight of the Champions League as they look to bounce back from their league defeat.
Tuchel led PSG to the final in Europe last term and Kovacic has praised the way in which he has reacted to his first reverse.
“I have seen a good side, the same as we have seen from the beginning,” said the Croatian.
“He’s calm but when he needs to say things, he says it.
“So we spoke in the dressing room, we analysed the game and we saw our mistakes, but we also saw positive things which were in this game.
“It was big loss, but it is a wake up call for the team.
“We analyse it and we are now totally focused for Wednesday and now just want to have a great game and improve every game.”
