The Brazilian was a target for the Red Devils during the transfer window as they tried to lure him to the Camp Nou.
And it has now been revealed, by Spanish newspaper Sport, that United offered Barcelona a mammoth £139m fee for the forward.
In addition, the Premier League giants also proposed to pay Neymar wages of £280,000-a-week but his father claims Barcelona refused to sell.
“United phoned Barcelona and got the answer that Neymar has a contract and is not for sale,” Neymar Snr told Sport.
“Everyone is calm. Neymar still has three years on his deal. We are happy. Neymar chose to play here and he is super happy in Barcelona – you can see that.”
