The Paris Saint-Germain head coach said the winger’s actions were ‘nervous’ after his dismissal in their 4-3 win over Bordeaux
The 28-year-old had an angry exchange with referee Willy Delajod and then appeared to sarcastically applaud the officials as he left the pitch.
However, Tuchel believed Neymar’s reaction was a natural one given he felt the PSG player had been fouled beforehand by Bordeaux’s Youssouf Sabaly.
Neymar is now set to miss PSG’s next Ligue 1 fixture at home to Dijon on Saturday.
“We have to talk about the whole situation,” Tuchel said of Neymar’s challenge in his post-match media conference.
“He is nervous and he reacts. It is human. He must not, but it is human. And the Bordeaux player does not even get a yellow card.”
PSG secured the points after a chaotic win thanks to two goals from Marquinhos and one apiece for Edinson Cavani – his 200th in all competitions for the club – and Kylian Mbappe.
It helped PSG increase their lead to 13 points over second-placed Marseille at the top of Ligue 1.
“The victory is the most important thing now because there are things to improve, it is clear,” added the German coach.
“The players lack a little confidence after a defeat. It’s like that. We can see that a lot of teams in Europe after a defeat it’s always a little difficult to regain spirit and confidence.”
Brazilian defender Marquinhos feels PSG must work hard to improve their defensive performances after leaking seven goals in their past two Ligue 1 games.
“On the one hand we are really very strong offensively, but on the other we concede a lot of goals,” he told Canal+.
“As defenders we really have to think about what we can do best. In this match it was mainly on set-pieces. We really have to work better collectively.”
