In Zlatan Ibrahimovic, Manchester United have recruited one of the most high-profile players in world football.
We take a look at five things you may not have known about the 34-year-old Sweden striker.
1. Ibrahimovic, born in Malmo in 1981, would frequently steal bicycles as a youth, a habit he says was necessary as he had no other transport for the long journeys to training sessions.
2. While Ibrahimovic, who recently declared he "came like a king, left like a legend" in regards to his time at Paris St Germain, is well-known for referring to himself in grandiose terms, the man he has said was his footballing "idol" is former Brazil striker Ronaldo.
3. In 2012 Ibrahimovic, then with PSG, became the first player to score for six different clubs in the Champions League - the others being AC Milan, Barcelona, Inter Milan, Juventus and Ajax.
4. That year also saw the Ibrahimovic-inspired verb "zlatanera", meaning "to dominate", officially recognised by the Swedish Language Council and included on its list of new words.
5. He has said that if he was not a footballer, he could see himself having a career in martial arts. While at Milan in 2010 he was awarded an honorary black belt by the Italian Taekwondo Federation.
