Manchester City manager Pep Guardiola can't believe Borussia Dortmund star Jude Bellingham is only 17 years of age.

The England international scored for Dortmund against City in their Champions League quarter-final on Wednesday, with Guardiola's side eventually prevailing 4-2 on aggregate.

Asked about Bellingham's performances over the two legs," Guardiola replied: "I cannot believe it, maybe he's a liar!"

"He's so good for 17-years-old, he's a fantastic player.

"There was one moment when he didn't get the ball from central defenders, how he shouts and demands that ball to him at 17 means a lot.

"I spoke with his manager, Edin [Terzic], and he told me what you see in these two games is like every training session."
