Sir Alex Ferguson has admitted he is 'proud to have been a rival, colleague and friend' to Arsene Wenger after the Arsenal boss announced he will step down at the end of the season after 22 years.
Ferguson and Wenger enjoyed the most enthralling and fierce rivalry in Premier League history in the late 1990s and early 2000s, with both Arsenal and Manchester United battling it out for the Premier League title year after year.
The rivalry dwindled after Arsenal moved to the Emirates, with United maintaining their dominance in English football while Wenger endured a barren run in north London.
