Paris Saint-Germain and Paris city officials.
After a Paris Council vote reopened negotiations.
Paris Saint-Germain have resumed formal talks to buy the Parc des Princes and explore a major redevelopment. The club are studying ways to expand the stadium from 48,000 seats to between 60,000 and 70,000.
City officials and PSG executives will meet weekly to assess valuation, transport, local infrastructure and construction feasibility. The project still needs a final binding council vote before any sale or expansion can move forward.
