Sarabia was selected ahead of Mauro Icardi and Cavani to start with Mbappe up front, and the former Real Madrid player curled home a fine opener from 22 yards in the eighth minute for his 10th goal of the season.
"I am coach. Somebody has to decide who comes off and goes on".
And the highly-coveted star later took to Instagram to hit back at the referee, telling his 132million followers: 'I just play football'. These are not good images, but we are not the only club that has to deal with this sort of thing.

On Neymar's birthday, Tuchel added: "It gives the impression that we are not 100 per cent focused and professional". "However, I am neither his father, nor handler, nor agent - I am just his coach".
"I do not want to say if I am going to be there or not, you will have to wait for tomorrow. But I don't really want to talk about it because then these things become big issues". "If there are hard truths to be said, I prefer to do it internally".
When the sides last met, Neymar had been criticised for showboating by Montpellier forward Andy Delort, and after such an action the referee took it upon himself to speak to the forward, who turns 28 on Wednesday.
The Montpellier attacker was vocal in his criticism of both players in the build-up to the match after a heated meeting towards the end of 2019, declaring that "at least Zlatan [Ibrahimovic] was very respectful" during their clashes.
Neymar, with his hair dyed pink, shook off an injury scare and raged with the match officials while Pablo Sarabia, Angel Di Maria, Kylian Mbappe and Layvin Kurzawa all scored along with a Daniel Congre own goal as PSG went 13 points clear of Marseille at the top of the table.
