FC Barcelona's Neymar Jr. writes on Twitter that the pop singer is "impossible to dribble".

Justin Bieber joined the FC Barcelona squad at their regular Monday training session today (November 21).

The club’s official Twitter shared video footage of the pop singer on the pitch, manning the goal and even managing to hit the back of the net – watch below.

FC Barcelona player Neymar Jr. saluted Bieber’s soccer skills on Twitter, writing: “Impossible to dribble this defender…”

Last month, Bieber joined the Manchester Storm ice hockey team for a practice session – and also scored a goal.

Meanwhile, Bieber appeared to cry during a show in Germany last week. The pop singer was playing a gig in Frankfurt on Wednesday night (November 16) when he choked up during a performance of the title track from his latest album ‘Purpose’.

It’s not the first time Bieber has cried onstage. The singer famously cried after his performance at the 2015 MTV VMAs. He later explained that he cried because the crowd didn’t boo him.

Bieber has made headlines for his random public antics in recent weeks. Last month, he tried to disguise himself in Amsterdam with a fake goatee and wig.

He also surprised a group of London school children by joining in with their game of football and was spotted in a Glasgow chip shop eating deep-fried haggis.

He also had to deal with having his trousers pulled down by a fan in Prague recently.
