Arsenal supporters can usually be heard chanting derogatory songs about Manchester United striker Robin van Persie whenever they visit Old Trafford - but on Sunday they also saved time to mock the Red Devils over their goalkeeper David de Gea.
Speculation is rife that De Gea will leave United for Real Madrid at the end of the season - Louis van Gaal recently admitted the club are looking at potential alternatives - and the Gunners' faithful took their opportunity to mock their old rivals by singing: “He’s off to Madrid, he’s off to Madrid, David De Gea, he’s off to Madrid.” (Scroll down to see the video).
This was after the home supporters had spent most of the match chanting: "David de Gea!" and "David de Gea, we want you to stay!"
De Gea limped off in the second half of the 1-1 draw against Arsene Wenger's men and was replaced by Victor Valdes, who made his Manchester United first-team debut.
Supporters were keeping a close eye on De Gea as the Spain international made his way to the dressing room, looking for signs of a possible wave goodbye, but the 24-year-old's body language provided few clues about his future plans.
De Gea expected to join Real Madrid
However, there's a growing feeling that it's a mere matter of time before Real Madrid make an official move for the man now widely regarded as one of the world's three best goalkeepers.
Former Manchester United captain Gary Neville, speaking on Sky Sports, does not expect De Gea to still be at Old Trafford come the start of next season.
“You saw the fans, they were signing his name,” Neville said. “You can hear them singing it now as the players do the lap of honour.
“They are singing his name in appreciation of the season he’s had. He’s been Manchester United’s player of the season and they’ll be saying, please stay.
“With his form this season I was always hopeful he’d stay but with the wave of noise in the press it just looked to have an inevitability about it.”
Neville: United should try to steal Bale
Neville believes United should take this opportunity to sign Gareth Bale in exchange, adding: “Manchester City, Chelsea, Arsenal and Liverpool will all want Gareth Bale. So if you are going to give Real a player I think it would make sense to try and get Bale and steal him in return for De Gea.”
However, Real Madrid know they will be able to sign De Gea, regardless of whether or not they offer Bale in return.
The Spaniard only has 12 months left to run on his current contract - and Manchester United are expected to sell, provided the offer is deemed satisfactory, rather than allowing the world-class goalkeeper to leave on a free transfer next summer.
