The 18-year-old proved beyond doubt that he’s not shy of the big occasion as he gave a man of the match performance to help Chelsea seal a 2-0 victory over the Reds.

He told BBC Sport after the game: “It was a good match. I’ve been training very hard to get this chance. Today I stepped up, took my opportunity. Great game and great victory.”

Chelsea boss Frank Lampard was pleased with the youngster’s performance and hailed it as top class.

Lampard said after the game: “I have absolute trust in Billy. I remember when he first came on against Sheffield United and we drew the game, people questioned this kid, but I have no problem with him.

“If he’s small in stature he’s huge in personality, and he’s also huge in talent. When I look at a midfield player I have lots of questions. Do you want to receive the ball in all positions and all moments? Yes, he does. Do you want to make angles and pick the right pass? Yes, he generally does. Will you put your foot in? Yes, he does.

“He does all the right things, and he’s humble. All his family were here tonight, his nan and grandad were down from Scotland, and what a performance. It wasn’t just as a youngster coming into the team, that’s one level, he performed like a top-class player going up against top-class players. It was a great night for Billy.

“He showed he is absolutely comfortable at this level. I’m the first not to get carried away, but if he can play like he played tonight then he’s comfortable at this level. He can get himself in and around the team. The players know that, they sense good players.

“He has trained with us all year. He moved from Academy to first team building recently, trains with us all the time and started against Liverpool because of how good a player he is. He put in an immaculate performance, a brilliant performance.”
