Marquinhos is ready to commit his future to PSG.
Yahoo Sport says the Brazilian is set to sign a new contract to 2021 at the Parc des Princes.
Marquinhos was a summer target for Barcelona and his decision to remain at the side who thumped them 4-0 in the Champions League will no doubt add insult to injury for the Catalans.
The 22-year-old joined for £26m from Roma in 2013 and also attracted interest from Chelsea.
