2015-2016, with Everton, Lukaku had 18 goals.
2016-2017 he had 25 goals! All in the EPL. He was possibly the best striker in the league that year!

Went to MU to play for shitty coaches, and
And in his first year, he had 16 goals and 7 assists
The following year he scored 12 goals...and that was without getting
Service from other players. Lukaku was a top 5-10 striker in league easily.

From Everton to MU, Lukaku was double digits in goals every season. Rashford and Martial haven’t even come close to any of that , with Rashford only getting 10 goals in a season.

As for Jesus, he is 23 years old, wayyyy too early to define his career. Like I said . His main problem his health, and his body being able to hold up......but the kid is talented as fock for club and country.
