# 3 Andriy Voronin
By far the oldest player and the only inactive player on this list. Voronin was a teammate of Jurgen Klopp in the German's last season as a player at Mainz. He joined Mainz as a teenager and Klopp saw the talent the Ukrainian possessed first-hand.
Voronin was given more first-team football by Klopp in his second season at Mainz and scored a decent nine goals. He exploded and ended up scoring 20 goals the following campaign. Mainz, however, failed to secure promotion that campaign and Voronin left to join Koln.
After just a season at Koln and three at Bayer Leverkusen, the Ukrainian striker joined Liverpool on a free transfer. Injuries and a series of unimpressive performances however saw him depart the Anfield club after two seasons. He scored six goals in 40 appearances for the Reds before returning to Germany where he joined Hertha Berlin on a season-long loan.
Voronin retired from professional football in 2013 after his contract at Dynamo Moscow expired and is currently the assistant manager at the club.
#2 Ciro Immobile
The Italian striker is widely renowned for his goalscoring exploits at Lazio but it is very easy to forget that. Like Kampl and Ginter, Immobile also joined Borussia Dortmund in Jurgen Klopp's final season in charge at the club.
He joined Dortmund from Torino for a reported €18.5 million after scoring 23 goals in 34 games for the Italian outfit. Immobile made his debut for Dortmund starting in the 2-0 Super Cup triumph over Bayern Munich.
Immobile garnered 24 appearances in the Bundesliga, starting just nine times and scoring three goals. He fared much better in Europe for Dortmund that campaign, scoring four goals in six games. Another three goals in the DFB-Pokal saw the Italian take up his tally for the season to 10 goals in 34 games.
The Italian was brought in to replace striker Robert Lewandowski, who joined rivals Bayern Munich that summer. Immobile but largely failed to live up to expectations and was sent out on loan to Sevilla the following campaign by Klopp's replacement Thomas Tuchel.
After Sevilla, he returned to Torino on loan before joining Lazio permanently where his career once again began its ascendancy. The 31-year-old has scored 150 goals in his five seasons at Lazio and is just nine goals away from equaling the all-time goalscoring record of the Italian giants.
#1 Kevin-Prince Boateng
A player famed for his many sojourns across clubs in Europe. His more famous spells include stints at AC Milan, Schalke and Barcelona recently. Boateng, however, played for Borussia Dortmund briefly back in 2009.
In his second season as a Tottenham Hotspur player, Boateng was loaned out to Jurgen Klopp's Borussia Dortmund in January. He played just three times for the London club all season.
He made just 11 appearances for the Black and Yellows and despite scoring no goals. Klopp was keen to sign the Ghanaian attacker permanently however the financial differences between Dortmund and Tottenham saw a potential deal fall through.
Boateng has since gone on to appear for 10 other sides since then and currently plies his trade at Serie B side Monza.
