Enzo Maresca said that Nicolas Jackson's precious red card should be avoided against Newcastle and that he would speak with the Chelsea striker.
Jackson was shown a straight red card for breaking his right forearm in the face of defender Sven Botman during the first half with Chelsea after the early goal of Sandro Tonali.
Bruno Guimaraes hit a late second for the hosts, who struggled in the second half against 10 players, but won a crucial victory in the race for the Champions League.
“The red card has undoubtedly influenced the game,” said Maresca. “In this stadium against this team it is already complicated and if you give them an extra player, it is even more difficult. But in general, I think, especially in the second half, we had three big opportunities. With 10 players it is not easy.
“As far as the red card is concerned, I think that if the referee decides for a red card, it is a red card. The only thing is in some different stadiums, sometimes it is more the sound that decides whether this is wrong or not.
'And then I didn't speak to Nico [to him]It's not the moment. We will probably talk to Nico in the next day. “
Asked if he thought the home crowd had influenced the decision of the red card, Maresca said: “No, I don't think so. I don't think about it. In the rest, my feeling from the touch line is that the sound sometimes decides whether it is wrong or not.”
Maresca hoped that Jackson, who will now miss the last two games of Chelsea against Manchester United and Nottingham Forest, would learn from the red card incident.
“What you have to do is avoid things like this, because you need all your squadron for the next game,” said Maresca. “But it happened, now he will come out for the rest of the season and hopefully he can learn for the future.
“The season for him is complete. He is our nine, he is our striker, the other is Marc Guiu that you know it has been injured from the past three months. He is almost back and we have to find a different solution for the last two games. These are both important games.”
