The 18-year-old - recruited from French side Lille during the close season - started his first game of the campaign against West Ham last week and marked the occasion with a goal. He will now be seeking a repeat performance when the reserves travel to Reading tonight.
The France under-18 international's powerful first half header made it 2-0 against the Hammers, eventually resulting in a 3-1 victory for Clive's defending champions
"I think what you see is a centre half who is physically very strong and powerful," considered the Development Coach. "Allied with that he can play and is comfortable on the ball.
"It is going to take him a while, he is learning about the English game, which is more fast and furious that perhaps he is used to. Physically he can handle it and he will only improve.
"His performance against West Ham was a very good start," added Clive, who believes Dorian was fortunate to have the ultra-competitive Charlie Lee - scorer of the first goal - alongside him in the heart of defence.
"I have to say that Charlie, over the last two games, has been outstanding. I think he has led by example and his range of pass and commitment to doing things right has been very evident in the two games.
"I am delighted with his performances and Dorian, I'm sure, will appreciate what Charlie does.
"If he shows the commitment that Charlie shows then he won't go far wrong."
Clive Allen has been suitably impressed with the impact made by summer signing Dorian Dervite on his introduction to the reserve team fold.
