Paris Saint-Germain are concerned their exit in the Champions League could lead to the exit of Neymar this summer.

Neymar arrived last summer for a world record fee but his first season has been problematic on and off the pitch.

Marquinhos sees retaining Neymar as key to PSG's eventual conquest of Europe's crown pleading with the striker "in particular" to "stay". "Neymar is a vital player for us, and he should have faith in our project, our team and our players".
