Paris Saint-Germain manager Thomas Tuchel said Neymar and Kylian Mbappe spur each other on to reach new heights.
The pair got on the scoresheet as PSG beat Amiens 4-1 in their final match of 2019 on Saturday.
"Neymar motivates Mbappe, and Mbappe motivates Neymar—that's good," Tuchel said, per Goal's Dejan Kalinic.
Asked if they could get better, he said:
"What does that mean, better? They play very well together. They've regained confidence and fitness; that's the most important thing.
"They defend with a lot of intensity. They're dangerous together because they like to play together.
