They are currently in third place, a point above Arsenal and three ahead of Spurs.
But Lamps believes that in order to be back challenging for the title - and the Champions League trophy - the club need to stick with a manager.
He said: "I don't think it's right to talk about any names while Rafa Benitez is in place now - although we all know his role and what is happening at the end of the season. I know people are talking about Jose Mourinho coming back.
"He's a fantastic manager and there is no doubt about his credentials.
"But it would be nice, whoever comes in, to have a good crack at consistency and staying in the job.
"And I think the fans would be happier if we get a manager who can stay more than half a season!"
