League Managers' Association chief Richard Bevan is ruing the sacking of Portsmouth Tony Adams, saying he didn't have enough time in the role.

Adams was appointed in late October and after only three months in the job was sacked.

"After speaking with Tony this morning on a couple of occasions, he was very disappointed, particularly for the fans, and very frustrated at only being given 16 games and three months," said Bevan.

"That isn't, in my opinion, long enough to build relations with the team and the club and all the stakeholders down there.

"Earlier in the season, Paul Ince had 17 games at Blackburn and it is a worrying trend. The average tenure at the moment for a manager is 15-16 months which is the lowest it has ever been.

"At the same time you recognise the pressures the club chairmen are under, particularly in the Premier League, in terms of the financial impact of not keeping your league status.

"You have to look at clubs like Manchester United and Sir Alex Ferguson, Arsenal and Arsene Wenger, Everton and David Moyes and Aston Villa and Martin O'Neill.

"These are guys who are given time to build those relations with the club and build a team. For example, I don't think Sir Alex won anything in his first four years at Manchester United.

"If you are prepared to do that, the statistics tell you that you will be more successful."
