PSG president Nasser Al-Khelaifi stands by the decision to sell David Luiz to Chelsea.

PSG have struggled in the league since his departure, but Al-Khelaifi insists it was the correct decision to let the 29-year-old leave.

“We know how things work on the inside. We can’t explain everything,” he told Le Parisien.

David Luiz is one of the best people I’ve ever met, but we already have two of the best centre-backs in the world in Thiago Silva and Marquinhos.

“We also have youngster from the academy who are pushing for a spot.

“Basically, we had our reasons for letting David Luiz go.”
