Tottenham boss Nuno Espirito Santo is eager to strengthen his options in the middle of the park.
Sarr, 18, has caught the eye of a number of clubs around Europe and his future is the subject of intense speculation this summer.
The Gunners were believed to be interested in the 23-year-old towards the start of last year, but the Brazilian made the move to the Groupama Stadium from Athletico Paranaense on a four-and-a-half-year deal.
The 25-year-old has made 180 appearances for PSG in all competitions, including 40 outings during the last campaign.
Kimpembe could face a battle for his spot next term, though, following the arrival of Sergio Ramos, and according to L’Equipe, the Frenchman could consider his future away from the French capital.
Les Gones said to be prepared to sell the 23-year-old for a fee as little as €25m due to their financial problems.
A recent report claimed that Spurs were preparing to beat the Gunners for the Frenchman’s signature in the current market.
