Barcelona face missing out on a deal for wantaway PSG star Neymar.
RAC1 says Barca have been given a deadline by PSG to noon today to make a final offer for the Brazil captain.
Barca have requested an extension by two hours to put together the bid.
The proposal is expected to include Ousmane Dembele - a player who has worked previously with PSG coach Thomas Tuchel at Borussia Dortmund.
Should Barca's offer fall short today, PSG will immediately turn to Real Madrid to close Neymar's sale.
