The prolific goalscorer said he was now hoping that could add to his Premier League opener and is keen to start mixing it consistently with the best players in the world.
"I am delighted to score and hopefully I can keep scoring now," said the 23-year old.
"As long as I'm getting chances I'm happy.
"I don't know who is on penalties this season as I've been out injured but I was always going to take the penalty.
"We are all new to the Premier League, it's the best league in the world, so to score in the best league in the world is what it's about."
