The One Player Sir Alex Ferguson "Would Have Done Anything To Keep" At Manchester United
United signed the Swedish legend on loan in January 2007 after Louis Saha picked up an injury.
Larsson was 35-years-old at the time and only stayed at Old Trafford for two months.
He returned to Helsingborg in March having found the back of the net three times in 13 games and Ferguson gave him glowing praise immediately after his final game.
"He's been fantastic for us, his professionalism, his attitude, everything he's done has been excellent," Ferguson explained following a 2-2 draw with Middlesbrough per Pundit Arena.
"We would love him to stay but, obviously, he has made his promise to his family and Helsingborg and I think we should respect that - but I would have done anything to keep him."
The Middlesbrough game also showed the Champions League winner wasn't afraid to "run his b**ls off" when he had to.
"In his last game in our colours at Middlesbrough, we were winning 2-1 and Henrik went back to play in midfield and ran his balls off," Ferguson wrote. in his second autobiography.
"On his return to the dressing room, all the players stood up and applauded him, and the staff joined in. It takes some player to make that kind of impact in two months.

"Cult status can vanish in two minutes if a player isn't doing his job. Yet Henrik retained that aura in his time with us. He looked a natural Man United player, with his movement and courage."
Ferguson continued: "On arrival at United, he seemed a bit of a cult figure with our players. They would say his name in awed tones.
"For a man of 35 years of age, his receptiveness to information on the coaching side was amazing. At every session he was rapt. He wanted to listen to Carlos (Queiroz), the tactics lectures; he was into every nuance of what we did."
Larsson himself would later admit he regretted not sticking around in the Premier League that little bit longer.
"The only regret I have in my playing career was that I didn't stay on for the rest of the season because I think if I did that I would have been offered a little bit more, maybe an extension on that," the forward said per Manchester Evening News.
"The problem with that was that I promised Helsingborg to come home and I wanted the kids to have somewhere they could call home."
The fact that such a short stint left such an impact proves the immense talent had Larsson had during his playing days.
