Barcelona fired out a Tweet about Kylian Mbappe before quickly deleting it after the 23-year-old scored a sensational hat-trick in the World Cup final.
At 2-0 down with 10 minutes to go, France looked down and out but a penalty from Mbappe in the 80th minute was quickly followed by a stunning volley a minute later, forcing the game into extra time.
With Argentina 3-2 up in the second period of extra-time, Mbappe completed his hat-trick with another spot kick three minutes from the end.

Barcelona let their guard slip by Tweeting out the word "Mbappe" with three exploding head emojis. But the Tweet from their official social media account was quickly deleted.
Mbappe has become the first player to score a hat-trick in a World Cup final since Sir Geoff Hirst for England in 1966.
However the Frenchman would eventually suffered heartbreak after Barcelona's former superstar Lionel Messi, who had scored twice in the match, led his team-mates to victory in a penalty shootout.
