Roberto Firmino has been worth his weight in gold for Liverpool since joining the Merseyside outfit from Hoffenheim in 2015.The Brazilian forward has been instrumental for the Reds during the Jurgen Klopp era, scoring 74 goals in 221 appearances.Firmino played his 222nd game for the Merseyside outfit against Sheffield United on Thursday night and he caught the eye of eagle-eyed football fans on social media - including Gary Lineker - with an exquisite touch on the stroke of half-time.The silky 28-year-old was on the edge of the box, offering Sadio Mane an option.Mane fired the ball into Firmino, who quickly adjusted and controlled the ball by putting his right foot behind his left leg.

“Did Firmino just do what I think he did?” Lineker tweeted to his 7.5 million followers. “Yes he did. Nice.”

What a touch.

BT Sport's video provides a clearer view...

The speed at which he does it is pretty ridiculous.

Firmino’s skill also led to plenty of other tweets from fans on social media…

Liverpool went into the half-time break thanks to an early goal from Mohamed Salah.

The Egyptian forward finished Andy Robertson’s cross to put the Reds 1-0 up.

If Klopp’s side win this match, they will restore their 13-point lead over second-placed Leicester City at the top of the Premier League table.
