Former Celtic and Barcelona star Henrik Larsson believes that a strong work ethic has been the biggest strength of Manchester United's summer signing Zlatan Ibrahimovic.

Larsson, who spent a brief loan spell at Old Trafford in 2007, claims that Ibrahimovic has worked really hard to achieve success and fame in his career.

"I think when a footballer has reached a certain level it's not having somebody handing it to you but a question of work ethic from the player," said the former national teammate of Ibrahimovic.

"He's been working hard and that is why he has got all the success and all the adulation from fans all over the world. I think [following individual players] is the way society is going with all the different kinds of access to the players. You have the internet and social media of course, and everyone can watch football every day. It's a lot easier to follow somebody's career now than it used to be."
