He toldSky Sports
"It was a good positive start, a solid professional performance. With the heat it was never going to be an end-to-end game, it was always going to be a game of moments.
"To win that was massive, Croatia are a good team and it will give the players a relief that they are comfortable in the group now. They'll be a bit more relaxed going into the game against Scotland and if they didn't win they could have been a bit anxious."
Asked about England’s chances to qualify for the knock-out stage, Rooney added:
"Scotland will be tough but after winning the game (against Croatia) I think England will comfortably go through to the next round.
"That's when I think it could get difficult for England - when you come up against a France, Portugal or Belgium - one of those top teams.
"There's a lot of quality in the squad, my only worry is a lack of experience - it's important Harry Maguire and Jordan Henderson get fit because they will be vital moving forward. Quality-wise they have as much as anyone in the competition and they have a great chance."
England will continue the group stage with a match against their old rivals Scotland on Friday.
