The League Managers Association have urged Manchester City owner Thaksin Shinawatra to rethink his plans to replace manager Sven-Goran Eriksson at the end of the season.
Thaksin met with Eriksson earlier this week and it now looks virtually certain that the Swede will leave his post despite keeping City on course for a creditable top 10 finish in the Premier League in his first season in charge.
LMA chief executive Richard Bevan insisted Thaksin should honour the three-year contract he agreed with Eriksson last summer following his takeover, and pointed to the success of Manchester United manager Sir Alex Ferguson as proof that the best results come with patience.
'Success for Manchester City is getting into the top 10, Sven has delivered that,' Bevan said. 'He has got two games to go and he is focusing on those two games to go, and we implore Dr Shinawatra to rethink his strategy and to keep Sven on for the three-year period.
'And I'm sure Sven will deliver, not only for the players, the club and the owners, but most importantly the fans.
'Just look across the way to Manchester United, one manager in almost 22 years, look what they have won and look what Manchester City have won in the last 20 years.'
Bevan reiterated the LMA's commitment to improve the way the game is run and urged club owners to think in the medium to long term.
He told Sky Sports News: 'We've got to look at getting better communication between the club's owners and the management.
'In the last 12 months we've had over 150 coaches and managers sacked in our game, and around 60% of those ended up through some sort of legal process.
'I think we have to remember that every time a manager gets sacked so do approximately two coaches.
'The public in Manchester want somebody looking after their club. Manchester City has been around for about a century, Dr Shinawatra has been around for about four months.'
