​The greatest managerial rivalries: Clough vs Revie, Ferguson vs Wenger and moreRivalries between managers often generate plenty of debate in professional football.Most managers have mutual respect for each other, but some are incapable of hiding their disdain for their rivals. Here are some of the greatest managerial head-to-heads.Brian Clough vs Don RevieArsene Wenger vs Jose MourinhoJock Stein vs Helenio HerreraSir Alex Ferguson vs Arsene WengerPep Guardiola vs Jose MourinhoSir Alex Ferguson vs Kevin KeeganRafa Benitez vs Sam AllardyceSir Alex Ferguson vs Rafa BenitezNeil Warnock vs Gary MegsonPep Guardiola vs Jurgen KloppWithout further ado, read on as we take a United Kingdom-focused look at some of the greatest managerial rivalries of all time.Brian Clough vs Don RevieThe hatred between Brian Clough and Don Revie ran so deep that it ultimately spawned a movie which sought to shine a light on the reasons behind the bitterness.Revie turned Leeds United into one of the top teams in the country during the early 1970s, but his methods did not find favour with the wider football world.The phrase ‘dirty Leeds’ is still part of modern-day football vocabulary, highlighting the depths to which Revie’s teams would stoop to win a game.When Clough was appointed to replace Revie in 1974, he told the players they should bin their medals because they ‘were not won fairly’.His comments led to a brutal television interview between the pair where they traded bitter insults at each other.Clough lasted 44 days at Leeds before being sacked, but ultimately had the last laugh by guiding Nottingham Forest to back-to-back European Cup successes.Arsene Wenger vs Jose MourinhoThe long-running spat with Arsene Wenger perfectly highlighted Jose Mourinho’s penchant for upsetting people.Mourinho lost just twice to Wenger in 19 games and was never slow to take a dig at his rival if the opportunity ever arose.The Portuguese described the Frenchman as a ‘voyeur’ in 2005 after he questioned Chelsea’s extravagant transfer policy.He then famously called Wenger a ‘specialist in failure’ in 2014, pinpointing the club’s nine-year trophy drought as the reason for his criticism.Mourinho was niggled by Wenger’s failure to mention him in his autobiography, claiming that he was embarrassed that he ‘never beat me’.The rivalry reached boiling point in 2014 when Wenger pushed Mourinho in the chest during a Premier League game at Stamford Bridge.Jock Stein vs Helenio HerreraHelenio Herrera guided Inter Milan to back-to-back European titles in 1964 and 1965.

Celtic and Jock Stein stood in their way in the final.Stein was bullish ahead of the game, telling the press that they would lift the trophy. Herrera refused to engage with the media, but was infuriated by Stein’s comments.Inter took an early lead from t
