The Manchester United striker was banned for the opening two games of the tournament after being sent off during the Three Lions' qualifying game against Montenegro.
It was not the first time Rooney had seen red in an England shirt after previously being given his marching orders during the 2006 World Cup quarter-finals.
However, Gerrard believes the 26-year-old has learned from his mistakes but feels he mustn’t stray from his natural game if he is to show his ability and make a lasting impact on the tournament.

The Liverpool midfielder told reporters: "I'm not going to tell Wayne not to be fired up for this game. That is what Wayne is all about, pressing, being aggressive in the right way.
"The reason he is world class is because of what he has shown up to today.
"Obviously we need him on the pitch. He is aware of that and he regrets the reaction when he got the suspension. I am sure he will behave himself well."
