English football is hurtling towards what promises to be a record-breaking campaign for managerial sackings. Micky Adams became the 42nd manager to be dismissed this season when he was fired on Sunday by Tranmere, rock bottom of the Football League. Forty sackings were recorded by the League Managers’ Association before the end of March, which was an all-time high, and the trend is set to smash its previous record of 46, set in 2006-07. Micky Adams left his role with Tranmere, who are bottom of the Football League, on Sunday . Gus Poyet is one of five Premier League manager to be sacked during this season . 2005-06: 25 . 2006-07: 30 . 2007-08: 29 . 2008-09: 28 . 2009-10: 23 . 2010-11: 34 . 2011-12: 28 . 2012-13: 36 . 2013-14: 32 . 2014-15: 40 . The Championship remains the most dangerous terrain. Malky Mackay, fired by Wigan this month, was the 17th to go in the second tier, where the average tenure is less than a year, thanks partly to trigger-happy clubs like Leeds. There have been 10 sackings in both League One and League Two, while the Barclays Premier League has been relatively safe, with five dismissals, not including those who quit — Alan Pardew from Newcastle and Tony Pulis from Crystal Palace. Amid the chaos, Arsene Wenger remains the longest serving boss with more than 18 years at Arsenal, followed by Paul Tisdale, who has been at Exeter for nearly nine years, and Karl Robinson, close to five years at MK Dons. Malky Mackay became the 17th Championship manager to be sacked this season earlier in April . YEARS/MONTHS . A Wenger (Arsenal)                            18/7 .

Robinson’s longevity at Milton Keynes is intriguing since he has resisted interest from several other clubs but he and chairman Pete Winkelman have forged a close bond. ‘There were times when I could have gone and I chose to stay,’ said Robinson. ‘And the chairman will tell you there were times when he could have moved me on, and had to think twice, because results haven’t always been great. ‘It’s increasingly difficult for managers and I’m very fortunate with my chairman. We have an amazing relationship and I’ll always be indebted to him for this opportunity. I would have felt a bit of a fraud if I’d walked away.’ Robinson joined MK Dons in 2007, initially as a coach under Paul Ince. He has seen the club evolve and his team are one point from the automatic promotion places with three games to play in League One. MK Dons are at home to Doncaster tonight and fans will have an eye on Preston, one point better off, who are playing at Notts County. As other managers look longingly at Winkelman’s patience, Robinson explains how the unique nature of MK Dons has encouraged continuity at the top. ‘This is a very controversial club,’ he said. ‘We’re growing an identity within an industry that was reluctant to accept us and I think that is harder to achieve if you chop and change your manager.’
