Sir Alex Ferguson has reflected on the ferocity of his rivalry with Arsene Wenger while they led Manchester United and Arsenal, with the Scot underlining the influence on Thierry Henry on how much respect he gave the Gunners.
Clashes between United and Arsenal were always fiercely fought contests between the two sides that dominated English football around the turn of the century.
There is a respect between the two managers now - as demonstrated in Ferguson's appearance in a documentary about Wenger titled 'Arsene Wenger: Invincible'.
Ferguson spoke not only of Wenger's influence on English football as a coach but particularly the moves he made to compete with United - particularly with the signing of Thierry Henry.
