The young midfielder will come up against his fellow former Arsenal trainee Julian Gray for the first time in senior football when Crystal Palace arrive at the Lane for an FA Cup third round clash.
Lewisham-born Gray, 24, moved on in July 2000 and hit the headlines with his match-winning display as Palace shocked Liverpool in the FA Cup at Anfield last season.
Rohan, three years Gray's junior but with 21 appearances under his best this season, will try to make sure there is no repeat of his heroics this time around.
"I know Julian well, we've been friends since I was a young boy and still speak to him regularly now," said Rohan, clearly looking forward to the encounter.
"He's a very good player and someone I always looked up to. He always used to give me advice. He was very highly rated at Arsenal.
"It's a dream to be able to play against him in the FA Cup. He's my friend but I'm just hoping we win. It will be nice to see him again and I'll speak to him afterwards.
"The bottom line is we all want to win. We know a couple of wins will lift everyone and we'll stick together and grind them out. That starts against Palace."
Rohan Ricketts aims to put one over an old friend tomorrow.
