The Croat scored a sweet long-range strike in the 66th minute that helped level the scoreline after a Sergio Ramos own goal put United ahead in the second half.
It was a superb outing overall for the ex-Tottenham midfielder whose performance as a second-half substitute was widely praised by commentators after the game.
Suker, who played for Real for three seasons in the 1990s, hopes that Modric will get more of a chance to break into the first team under Jose Mourinho for the remainder of the season.
"I hope that he can continue to show that he has the qualities to become an important player for Madrid. The match against United showed that he can lead the team in big games," Suker told Marca on Thursday.
"In an important match, under pressure and in a tough stadium to play in, we've seen what he can do. He's an outstanding player and scored an amazing goal at a key moment.
"He's proven how good he is, that he has the talent and personality to take control of the team and go in search of victory.
"He has always worked hard without complaining. This will be a big confidence boost for him.
"He showed everybody what he's capable of. Modric is a fantastic player and he proved his worth at a big moment.
"I wish him all the best and that he carries on showing, little by little, that he has the talent to be an important player at Real Madrid."
Ronaldo scored the other goal for Los Blancos three minutes after Modric's goal to ensure progression to the last-16 stage of the Champions League.
