Brown fully aware of Hibernian duo
Riordan returned to Hibs last summer following a frustrating two years under Gordon Strachan at Celtic Park in which he was rarely used.
Ironically, his goal in the 1-1 draw against Rangers at Easter Road on Wednesday night arguably did more to help Celtic's championship bid than anything he did while at Parkhead.
Riordan's striker partner Fletcher was the subject of an unsuccessful bid by Strachan in January.
However, he turned the disappointment of not being able to join his boyhood heroes in to a positive, recently picking up the Scottish Football Writers' Young Player of the Year award.
The Scotland striker also picked up the equivalent prize from the SPL's sponsors.
Brown believes Riordan will be out to prove Celtic were wrong in getting rid of him, while Fletcher will want to entice the Parkhead club in to making another bid to take him to Glasgow.
The Hoops midfielder, who will shrug off an ankle knock to play against his former club, said: "Most people have seen Derek and Steven playing - they are good players.
"I think Derek will want to prove people wrong and show that he could have made it for Celtic.
"He's scoring goals for fun at Hibs and (he wants to show) that he could have done it here at Celtic as well.
"You saw his goal against Rangers; the way he took it was fantastic.
"There are only a few people in the SPL who could do that and Derek is one of them.
"Steven is a lot stronger than what he used to be; he is holding the ball up and he is one of the main assets for Hibs."
Brown is expecting a typically-hard fought encounter at a stadium where Celtic lost 2-0 in December.
With that in mind, the Scotland midfielder is not too concerned about the fact goal difference may yet play a part in deciding the destination of the title.
"Hibs will have a few players back and I think they will come out fighting," he said.
"They will play good football, they have height and they will be dangerous at set pieces.
"They will play just as well as they played against Rangers, I'm sure.
"I will be nervous going in to it but you just have to go and play football and hope that at the end of the 90 minutes you have come out on top."
"We are aware of that (goal difference) but we will just go out and play our game and as long as we win then it's a positive for us."
