Chelsea came from behind to thump the Irons at London stadium.
Pedro struck on the night and later said: "We started the game having gone one goal down, but we showed our togetherness today to win the game.
"I think we know our power. When we started the game, the first thing we thought about was winning. We’ve got so much power in the team. Cole Palmer was out today, but we played Estevao Willian and he showed his quality. It’s good to have a team like this.
"With different players scoring today, that will help give confidence to the team. That confidence will help us keep going.
"To have the first win away is very important for us. It helps to prepare us for other games. You never know, you can go 1-0 down, but if you have the confidence, then you can change the game."
He added: "I’m from Brazil, and the connection between the players and the fans is so important. Of course, we’ll always be going to give 100 per cent to make them happy. I’m very happy to play in front of the fans and show them our quality."
