The two PSG stars made headlines last season after clashing over penalty-taking duties, but it seems all is well between the pair after Neymar handed over the duty to Cavani on Wednesday evening.
Cavani netted from the penalty spot as PSG romped to a 5-0 victory to top their UEFA Champions League group ahead of Real Madrid.
"It was a nice gesture. Everyone can see, Ney is very sensitive. He gave the ball to Edi, and it's a good symbol for the team," Tuchel was quoted as saying by Bleacher Report.
"Neymar was already super important and very good at Montpellier . He was decisive for us and he's getting better. He worked hard today, won lots of balls and did well defensively. He's finding his form. It's easier for him now.
"Cavani lacked rhythm, and that was my fault and the fault of injuries. It was important for him to score. It's the best way to get confidence and I'm very happy for him."
