Aston Villa manager Paul Lambert admits to being "disappointed" at comments made about him by Norwich chairman Alan Bowkett over his departure from Carrow Road this summer.
But Lambert today revealed that he is also being sued by Norwich and retains the full backing of the League Managers' Association (LMA).
Bowkett said: "The manner of Paul Lambert's departure was no surprise because he has walked out on every club he has managed.
"You can't complain because you know what you are getting, but I felt he could have left in a more dignified manner."
Lambert hit back and said today: "I'm extremely disappointed that senior officials at Norwich have made comments in relation to myself.
"I'll let him (Bowkett) say what he has got to say and we'll see what happens.
"It will go before the Premier League managers' tribunal. The LMA are acting on my behalf. They supported me at the time and still are.
"What Norwich haven't made public is that they are suing me.
"It is disrespectful and wrong to that tribunal for me to comment anymore. That's the way I'm going to leave it.
"My main concern is Aston Villa."
Lambert added: "Am I concerned Norwich fans are only hearing one side of the story? In a word, yes."
