#3 Romelu Lukaku - Inter Milan
Romelu Lukaku's Manchester United spell might have split opinion, but there is no denying his influence at Inter Milan.
The Belgium international left Manchester United to join Inter Milan for a club-record fee of €75 million, as a direct replacement for Mauro Icardi. Lukaku has fit Antonio Conte's system perfectly and has led Inter Milan's line with aplomb so far.
The 27-year old formed a solid attacking partnership with Lautaro Martinez last season, and scored 23 goals in 36 league games. The former Everton man has 11 goals in 12 games so far and has recently been linked with a move to Manchester City.
#2 Ciro Immobile - Lazio
After failed stints at Borussia Dortmund and Sevilla, Ciro Immobile made a return to his favourite hunting ground; the Serie A.
Lazio signed him in 2016 from Sevilla for €10 million, and he has not looked back. Now the 30-year old is considered as one of the most lethal strikers in the Italian top-flight. Since making his debut for Lazio in 2016, he has made 194 appearances in all competitions and scored an incredible 139 goals.
The Italy international was in sensational form last time around, scoring 36 goals in 37 Serie A games. This led him to win the European Golden Shoe as well as the Capocannoniere title. He has nine in 12 games this season.
#1 Cristiano Ronaldo - Juventus
Cristiano Ronaldo continues to be Juventus' most important attacking player, and alongside Zlatan Ibrahimovic is ageing like fine wine.
While the Portugal international may not be the Ronaldo of old, he has established himself as an elite-goalscorer. The 35-year old joined Juventus from Real Madrid for a club-record fee of €100 million in 2018, and has won the Serie A in both his seasons so far.
The former Manchester United star scored 31 goals in 33 games last season as Juventus triumphed in the league, and his importance has been evident this time around as well. He has 12 goals in 10 games so far and Juventus look blunt whenever they are without their talisman.
