The Scot enjoyed three hugely successful years at Carrow Road, guiding the Canaries to consecutive promotions and an impressive first season in the Barclays Premier League before leaving on acrimonious terms.
The match marks his second return to Carrow Road since leaving, having beaten his old team 4-1 in the Capital One Cup earlier this season. And Lambert insists his links with the club will be far from his thoughts if Villa beat 14th-placed Norwich and worsen their plight while boosting his own side's survival bid.
"I think if you get caught up in my connection there it deflects from the game," he said. "It's not about me going back there because I've been back already. I had three fabulous years there and took a team from League One, built it up, the crowd bought into it, the lads I worked with were fantastic.
"It's another game and I'm looking forward to going down there. I have fantastic memories there but it has gone.
"I'm looking forward to it because I had three really enjoyable years there that I don't think anyone would have seen coming.
"The players I worked with were fantastic and one or two are still there. I probably know them better than they know themselves, really.
"There's a few teams right in the relegation battle anyway. We know we've got a hard game there but we're certainly playing well enough. That's the big difference.
"My job is here. We have to win. If our fans are anything like they were for the cup game then we'll be taking a ferocious support down there. It will be a tough game but we're certainly playing well."
