The Scot has watched on as Sherwood has turned his old side's form around in spectacular fashion.
Paul Lambert has told Sky Sports News HQ that he bears no grudges towards Aston Villa over his sacking, despite believing that the club’s financial constraints gave him an impossible task to live up to public expectations.
After two previous relegation-threatened campaigns under his watch, Lambert managed to get Villa off to a promising start to this term, guiding them to second place in the table after a four-game unbeaten start, which included a 1-0 win at Liverpool.
However, after being handed a new long-term deal in mid-September, the club’s subsequent form proved nothing short of disastrous, as a run of just two wins in 21 Premier League matches again put their top-flight status under threat.
Dismissed in February with the club in the drop zone following a dismal 2-0 defeat at Hull City, successor Tim Sherwood has since steered the club to the brink of safety with two games left and earned widespread plaudits for revitalising the team's performances.
Lambert himself has not been surprised to see his old side doing so well under the ex-Tottenham head coach considering the talent available to him, but still feels that his record at Vila stands up due to having to work with a reduced budget.
“There was no problem on [the sacking] front,” he said on Thursday morning. “But it is a massive football club and everyone says we should be in the top six or seven but that could never have been sustained by doing what we were doing.
“The reality is it was never going to hit that height. In the Premier League you have to spend just to stand still and the club is financially stronger now.
“I’ve got nothing bad to say about Aston Villa, it’s a brilliant football club and there is no animosity from me whatsoever. I’m delighted that Tim is doing well and hopefully they can win the FA Cup.
“I’ve always said they will stay in the league when everyone is fully fit and that is exactly what is going to happen.”
Continuing on the improvement the team has had since Sherwood’s arrival, Lambert added: “I’m not surprised. I’d be more surprised if he hadn’t got a reaction when he walked in the door.
“I don’t know Tim as a guy but I’m delighted for people like Tom Cleverley, who I brought to the football club.
“Tom’s starting to score a few goals, Christian Benteke’s back to his best and Fabian’s doing really well and in the England squad, so I’m not surprised the way the lads have played.”
Since his sacking, Lambert has been touring around Europe in a bid to pick up a few coaching tips and stresses that he is now eager to get back into the game to prove some of his doubters wrong.
“I’ve really enjoyed my time off,” he said. “I went to Madrid, Bayern and Dortmund, so it’s been great, but do I want to get back in? – Absolutely.
“I love the game and the pressure of it and you want to go to the highest level you can possibly go. I’m not fazed by anything to be honest. I want to get back in.”
