Romelu Lukaku continued his scintillating start to the season with Manchester United, scoring a seventh goal in all competitions on the way to an emphatic 4-0 victory against Everton at Old Trafford yesterday.

When the Belgium international arrived for a sizeable price tag – an initial £75million as well as £15millon in add-ons – there were those that wondered if he would hit the ground running straight away.

Another burning question on people’s minds was whether he could go on to enjoy the same success as Wayne Rooney, the man who moved in the other direction, returning to his boyhood club.

After the 31-year-old cemented his reputation as one of United’s best-ever players, becoming the club’s all-time leading goal scorer and eclipsing Sir Bobby Charlton’s tally of 250, it seemed like the task of replacing him would be extremely difficult.

United manager Jose Mourinho decided to enlist the help of Lukaku to fill the void and when you look at his stats over the past few seasons it is clear why the Red Devils boss made that choice.

Lukaku has regularly demonstrated a ruthless efficiency in front of goal, being just one of three players alongside Olivier Giroud and Sergio Aguero to reach double figures during the last five Premier League seasons.

Although half of his 85 strikes in the league before joining United were using his left foot, a quarter also came from his right foot and head demonstrating quite capably how much of a complete player he has become.

If you look back at Rooney’s career with United, he only scored more than 20 Premier League goals in two of those 13 seasons as a Red. Lukaku already has five league goals and there is a long way to go before we are even a quarter of the way through the campaign.
