The England striker was frozen out by the now Blackburn Rovers manager.
This evening however he has to cast his mind to all things Blackburn Rovers, his current team, who are struggling at the wrong end of the table.
In that game he could face off with his former Aston Villa striker Darren Bent.
Lambert effectively froze the former England international out of the first-team at Villa Park and reports were often rife regarding a strained relationship between the pair.
However, speaking prior to the game this evening, Lambert insisted there was nothing seriously wrong with their relationship.
He is quoted by the Daily Mail as stating:
"Benty was alright. Benty had his views and I had mine and I was probably right!
"No doubt we'll have a talk, there was no problem. That's what happens."
Bent himself has only recently played himself back into contention for the Derby County first-team after a period out under the management of previous boss Paul Clement.
His career has struggled to get off the ground in recent times and he is out of contract at the end of the season.
Whilst Lambert appears to suggest there is nothing personal between the two do not expect to see Bent heading to Ewood Park.
