The Nigerian youngster made his fourth Premier League start for Manchester City on Saturday and scored twice in a 4-0 win at the Etihad Stadium.
Iheanacho has impressed every time he has been given a chance by Manuel Pellegrini this season and the 19-year-old has quickly become a fan favourite.
His Champions League career has so far been limited to two late substitute appearances against Dynamo Kiev and Paris St Germain, but Pellegrini did not rule out Iheanacho playing a part on Tuesday in one of the biggest games in the club's history.
Real Madrid visit the Etihad for the first leg of City's first Champions League semi-final, offering Iheanacho the chance to challenge himself against the likes of Cristiano Ronaldo, Karim Benzema and Gareth Bale.
"I think I should dream about that because it's a great team to dream about," he said
"It would be a dream come true to play against them.
"Ronaldo and Messi are the greatest players on the planet so I think playing against them is a big thing to anyone. It would be a big thing to me if I play against him on Tuesday."
Iheanacho impressed with his all-round play against Stoke, not just scoring two goals but also winning the penalty that Sergio Aguero converted for City's second.
The teenager did not want to talk up his chances of playing on Tuesday too much, saying: "It was a great performance for everybody, everybody really did well, so it depends on who the manager picks. Everyone is fit to face Madrid.
"(If I was picked) I would feel very great, I would feel very happy. I would grab the opportunity and really work hard."
