What a signing Roberto Firmino has proved to be for Liverpool.
The Brazilian arrived for £29 million last summer when Brendan Rodgers was in charge and struggled to apply himself on Merseyside.
Fast forward a year and it's a completely different story, with Firmino firing on all cylinders alongside Philippe Coutinho and Sadio Mane under Jurgen Klopp.

He was in fine form once again for Liverpool against West Brom on Saturday night, producing a lovely assist for Mane's opener after some wonderful build-up play.
From Coutinho's dummy and Emre Can's pass, the 25-year-old played an inch-perfect cross to the far post for Mane to volley home emphatically.
Firmino has particularly become renowned for his trickery at Anfield and two moments against the Baggies suggested why that's the case.
In the two videos below, Firmino set up Nathaniel Clyne with an intelligent flicked pass and later bamboozled Gareth McAuley with a roulette, also winning a free-kick.
FIRMINO TO CLYNE
FIRMINO VS MCAULEY
Firmino has thrived in the No.9 role this season - he's scored three goals in the Premier League so far - and successfully kept Daniel Sturridge out of the team.
Klopp's gamble has certainly paid off and he recently explained his decision to deploy the 25-year-old at the peak of a false nine formation.
He said on Sky Sports last month, per the Mirror: "Roberto is a player who is always involved. In all offensive actions and all defensive actions.
"He really likes doing things like this, because it's a natural skill that he knows.
"It's a nice opportunity to win the ball and be close [enough to the goal to score], that's why he's doing it.
"He doesn't think too much, he's an instinctive player; that's really, really strong in these situations. He can play nearly all offensive positions - that's how it is."
