Lampard's former England team-mate Bent, who played for both Derby and Aston Villa, believes he would be better-served staying at Pride Park for another year – irrespective of whether the Rams go up or not.
Bent told the Mirror: “Frank has done a fantastic job, especially the way he's kept them believing when it looked like they were going to fall short of the towards the end of the season.
“That's a fine achievement for a first-time manager in his first year doing the job. I know there are Chelsea fans who would put him in charge at Stamford Bridge tomorrow, and I would agree that Frank is destined to manage at the top level.
“But you are talking about a different animal at Chelsea – the step up is massive. We've seen a lot of managers, who have been around a lot longer than Frank has, go there and fail. And we know it's not a forgiving club, patience wears thin pretty quickly, and if you aren't winning trophies within a year or 18 months, usually you're out the door.
“I would like to think that whether or not Derby are promoted on Monday, another year is not going to do him any harm in the long run."
