Back in 2007 teams from across Europe were chasing a young talent from Iceland called Kolbeinn Sigthorsson.
He had already made his first-team debut for his first club HK Kopavogur when teams began to show an interest in his services - but it was Arsenal who looked like they were going to get a hold of the teenager.
He went on two trial spells in London to earn a deal and Arsenal wanted to sign him - but he instead decided to join Dutch side AZ Alkmaar.
After coming through some bad times with injury he went on to play 43 games in the 2010-11 season, scoring 18 goals in an impressive campaign - especially in the Eredivisie.
That form saw him earn a €4.5 million move to Dutch giants Ajax - and he has been linked with the likes of Newcastel United and QPR during his time in Holland.
But how close was he to joining Arsenal?
Very according to Marcel Brands. Brands, who is now sporting director at PSV Eindhoven, was in the same role at AZ when they agreed a move to bring him to the club in 2007.
He has been speaking to the Dutch paper De Telegraaf about the transfer this weekend. And he says that it was the input of Manchester United's current boss Louis van Gaal that convinced Sigthorsson to reject Arsenal's advances.
"He first appeared unattainable because Arsenal were emphatically in the picture. But after discussions with his agent and brother, he was introduced to coach Louis van Gaal. Louis won him over in his own way. Sporting reasons convinced him."
So the current United boss convinced a seemingly done Arsenal deal to change his mind. That will definitely please United fans.
