Manchester United scouts have become conspicuous at PSG games in recent weeks.
Le Sport 10 says United boss Louis van Gaal is willing to spend big for the right signings in January and PSG striker Edinson Cavani is on the agenda.
Doubts persist over the future of Robin van Persie, despite his stunner against Hull City, while Radamel Falcao needs to prove his finesse for his loan from AS Monaco to be turned into a permanent deal.
Cavani is under consideration for Van Gaal, who is also trawling the Brazilian market for a new striker.
Atletico Paranaense ace Douglas Coutinho is being watched by United.
