Former Manchester United manager David Moyes believes his sacking and the subsequent appointment of Louis van Gaal has ended the club's tradition of planning for the future.

Moyes was dismissed nine months into his six-year deal at Old Trafford after failing to qualify for the Champions League in his first season in charge.

Upon the Scot's appointment comparisons were drawn between Moyes and Sir Alex Ferguson, who announced his retirement from United last May, and having been handed a long contract was expected to be give similar time at the helm.

However, Moyes was handed barely a season to adapt to the demands at United and he admits the club's long-term thinking adopted under Ferguson is a thing of the past.

"I never had the chance to thank the Manchester United supporters for the backing they gave me during my time as manager," he wrote in the Sunday Times. "I wish them every success in the future.

"They now appreciate, I am sure, that things are changing at their club and it could well be that gone are the days of long-term planning. They were fully aware of the task I had. It was unfortunate I wasn't given more time to succeed."

Moyes' harrowing experience at United was expected to see him take time out of the game, having also spent 11 years at Everton though the manager admits offers have already come in.

Though Roy Keane is expected to take over, Moyes had been linked with the vacant managers position at Celtic and he admits to being tempted into returning to the game.

"Since leaving [United], I have received some very good offers and am tempted by one or two of them," he added.

"I have not closed the door on anything and am open-minded about my next step in management, and whether it will be in the UK or abroad.

"Another possibility is that I may choose to have a break and enjoy watching and observing football throughout the world. What I do know for sure is that I have moved on."
