But it looks like the Northern Irishman's investment in Roberto Firmino is starting to pay dividends for Jurgen Klopp.
Firmino was a Brazil international playing at the Copa America when he signed for Liverpool, off the back of a successful spell at Hoffenheim, but £29 million looked like a costly deal and returned just one goal in his first 24 games for the club.
January, however, has seen a transformation in his fortunes and Saturday's incredible 5-4 victory against Norwich City saw Firmino play a vital part, scoring two goals and assisting one more.
Not only does it see him now on a veritable hot streak but it was the kind of performance not seen in a Reds shirt since the now-departed Raheem Sterling nearly two years ago. Is this the start of something special for the 24-year-old?
