Midfielder Dean could earn his first England cap tonight after being called into Peter Taylor's Under-21 squad for the friendly against Holland at Pride Park.
It would be the latest step on a ladder that has taken Deano from the Academy to the reserve team, first team and, hopefully, the international stage.
Few will forget his amazing two-goal full home debut against Everton on New Year's Day and development coach Clive says that's what the reserve lads have to aspire to.
"It's fantastic for Dean," said Clive, who will travel to Pride Park to hopefully watch Dean's first international appearance first hand. "It's important for the club and it shows the progress he's made as an individual.
"We can remind the lads that he's come through the reserve team, he's gone into the first team, taken his opportunity an stayed involved in the first team squad and he now gets international recognition.
"It's the next level for him, it will be a great experience and I'll be going up to hopefully see him play some part at Derby.
"It's progress for the club when players are promoted from the reserve team to the first team group and then get international recognition. It's good to see and everyone is delighted for him."
Clive Allen says Dean Marney's example is a shining light for the rest of his young lads in the reserve squad.
