Tony Adams leaves Portsmouth's training ground after saying his farewells
Tony Adams has admitted he was surprised to have been sacked as manager of Portsmouth.
Adams, 42, left the club after winning just two of 16 Premier League games since taking over on 28 October.
He told BBC Radio Solent: "I am a little bit surprised but results haven't been good.
"I haven't had a lot of time and I certainly haven't had the financial backing. We've had a few injuries as well and that's tough to take."
He added: "I'm still up for the challenge so I've got mixed feelings."
Adams' final game in charge was Saturday's 3-2 home defeat by Liverpool, and he admitted he could not have asked for any more from his players or fans.
"The guys worked their socks off at the weekend and I've really got to thank the fans," he said.
"I thought they were magnificent for the whole game and were really supportive of me and the team.
"That gave me some inspiration and encouragement ready for the challenge ahead."
Adams conceded his record as manager had not helped his cause for keeping the job.
"I don't think the results have been good, it must be said," he admitted.
"We have been making a lot of mistakes. We are in the results industry and the owner and chairman will point to that. I'm not going to bang on about excuses.
"I think I could have turned it around but it was not to be."
Striker David Nugent, who struggled to make his mark after his £6m move from Preston in July 2007, has recently found his form under the ex-Arsenal man, with three goals in his last four outings.
He said that he believed the club should have given Adams more time at Fratton Park.
"He gave me a chance and I was happy for him to stay. I thought he deserved a few more games but it's the chairman's decision and we'll see who comes in next," said Nugent.
"He called me aside and said I'd done well for him in the past few games, scoring a couple of goals. He wished us well for the future and just walked out; that was it really.
"There's 11 teams who could go down. We have to get a bit of stability at the club, get a few wins and get out of there. I don't have a clue about management but we need someone who can come in and is up for the scrap.
"The players are up for it so we just need someone who can come in and get a few wins."
League Managers Association chief executive Richard Bevan has offered his support to Adams, while also calling on clubs to give managers more time to make their mark.
"After speaking with Tony this morning, he was very disappointed, particularly for the fans, and very frustrated at only being given 16 games and three months," Bevan said.
