Cardiff City boss and Manchester United legend Ole Gunnar Solskjaer has insisted that he was not offended by Roberto Martinez’s critical comments about changing a manager mid-season to improve results in the long term.
Speaking on the BBC, the Everton manager said, "It is difficult. It is very rare you get a real improvement for the long-term.”
"In the short term they sometimes get a positive reaction, but a change rarely affects things in a good way for the long term.
"Overall you don't want to see those sort of changes and I personally don't believe the quick turnaround of a manager will give you long-term success unless you appoint the right man."
Solskjaer replaced Malky Mackay in January after the Scot fell out with controversial owner Vincent Tan.
However, despite general optimism about results improving, Solskjaer’s side currently sit in 18th place in the Barclays Premier League, behind 17th placed West Brom on goal difference.
In response to his friend's comments, the former United striker said, "I know for a fact Roberto never ever mentioned me or Cardiff," he said.
"I know it's not a dig at Cardiff - it's just general research that's been made.
"When you go on all these courses we do, [Uefa] pro licence and all these things you get stats.
"And the stats say you get a quick reaction and then sometimes it just flattens out and maybe even goes down.
The Norwegian then pointed towards the example of Mauricio Pochettino at Southampton as evidence that mid-season managerial changes can be successful.
Pochettino replaced Nigel Adkins as Southampton manager in January 2013, his burgeoning side currently sit in 9th place in the league and Luke Shaw, Ricky Lambert, Adam Lallana and James Rodriguez are all contenders for a place in England’s World Cup squad.
With Cardiff set to face Everton in one of today’s fixtures, Solskjaer will be hoping that his side can continue their recent good form after a 3-1 win against fellow strugglers Fulham last weekend.
