Monaco vice-president Vadim Vasilyev admits the club could not turn down the amount of money offered for Anthony Martial.
The French striker moved to Manchester United on deadline day for a fee worth up to £56 million, a record for a teenager.
However, Vasilyev said on the club's website: "We really wanted to keep (Martial) on the team, but Manchester has made an incredible offer, almost the close of the market, an offer that neither the club nor the player could refuse. That's football.
"(It is) evident that certain clubs - especially the British - have unprecedented resources, and it is hard to resist."
Wayne Rooney will be presented with an award next month if he breaks or equals England's scoring record in the coming days.
With England facing minnows San Marino on Saturday and then taking on Switzerland at home three days later, Rooney stands a good chance of breaking Sir Bobby Charlton's all-time scoring record over the next week.
The England captain's current total stands at 48 goals, just one shy of the World Cup winning former Manchester United forward.
The Football Association (FA) does not plan to honour the striker until next month, however, as it does not want to be too presumptuous on the matter.
It is understood that the FA instead plans to honour the Manchester United forward with some kind of trophy or plaque before England's next home game against Estonia on October 9.
Juan Mata expects his Spain and Manchester United team-mate David de Gea to remain professional, despite the disappointment of his failed move to Real Madrid.
The 24-year-old goalkeeper, who has not featured for United this season, was the subject of a bid from hometown club Real on Monday, but the deal fell through due to a miscommunication.
"He seems calm to me, like he always is," Mata told AS.com. "He's had a testing few days, but I've been his friend and by his side throughout.
"It's good that he's here and just thinking about these two matches. He will be professional just like he always has been throughout his career.
"David is a professional and he will remain that way. He's a great goalkeeper and any team would be boosted by his presence. The fans will get behind him, and all of us."

Aaron Lennon has joined Everton from Spurs on a three-year deal for £4.5m.
The nippy 28 year-old winger spent the second half of last season on loan at Goodison Park after seeing his first team opportunities at White Hart Lane restricted.
Manager Roberto Martinez told Everton.com:
We are delighted to welcome Aaron back to Everton. We know we are getting a player our fans know inside out. He had a major role in the second half of our season and we're looking forward to Aaron kicking on and continuing to enjoy his football, as well as being the productive player we know he can be.
He is well-respected in the dressing room, his experience in the Premier League is immense and he will immediately add to our squad and to the ambition we have as a club.

Manchester United have announced the signing of forward Anthony Martial from Monaco on a four-year contract.
Louis van Gaal took his total expenditure as Manchester United manager to over a quarter of a billion pounds following the signing of Anthony Martial from Monaco.
United failed in their last-minute bid to offload goalkeeper David de Gea to Real Madrid on Monday night, but there were no late hiccups regarding Martial.
The Old Trafford club confirmed on Tuesday afternoon they had completed a deal to sign the 19-year-old French striker for a fee believed to be worth in excess of £36million.
Martial becomes the 12th signing of Van Gaal's reign. In total, the Dutchman has spent around £261million on new additions since he took over as manager last summer.
The 19-year-old also becomes the most expensive teenager in the history of football, eclipsing the £30million fee Van Gaal paid for Luke Shaw last year.
Monaco, who signed Martial from Lyon two years ago, rate the player highly, but the Ligue 1 club admitted United's offer was simply too good to turn down.
Monaco vice-president Vadim Vasilyev told the club's website: "We wished to keep him this season but Manchester United made an incredible offer that neither Anthony, nor AS Monaco, could refuse."
The forward, who scored 15 goals in 70 appearances for Monaco, has signed a four-year contract, with the option of another year.
