Manchester United welcome rivals Manchester City to Old Trafford on Sunday afternoon aiming to become just the second side to take points off the Premier League leaders this season.
The Citizens have slipped up only once in their opening 15 matches, being held to a 1-1 draw by Everton on matchday two, and are eight points clear of their second-placed opponents heading into this weekend's crunch fixture.
One of the areas City have outperformed their neighbours is in attack, having scored 46 goals compared to United's 35, with Sergio Aguero (9) and Romelu Lukaku (8) leading the scoring charts for their respective sides.
After a storming start to the season Lukaku has since stuttered somewhat, bagging just two goals in his last 13 outings in all competitions.
Ahead of the first Manchester derby of the campaign, Sports Mole looks at how the Belgium international has fared against Pep Guardiola's men in the past.
West Bromwich Albion
Played: 2
Scored: 0
Having been left out of the squad entirely for Chelsea's two meetings with City in the season prior, Lukaku first featured against the Citizens in 2012-13.
En route to establishing himself as one of the most talented young strikers around, finding the net 17 times during that breakthrough campaign on loan at The Hawthorns, the Belgian was ultimately left frustrated in both league games as he failed to get off the mark in a combined 99 minutes.
Everton
Played: 10
Scored: 5
Lukaku swapped West Brom for Everton in 2013, initially signing on loan before completing a club-record move of £28m the following year. During his time at Goodison Park, the 24-year-old could boast a record of a goal every other game against the Citizens, including one in both of last term's fixtures.
After opening the scoring in a 1-1 draw at the Etihad Stadium 14 months ago - a game now best remembered for Maarten Stekelenburg saving two penalties - Lukaku then did likewise in the reverse fixture earlier this year, with the Toffees running out comfortable 4-0 winners.
Those goals came on the back of a four-match scoreless run in that particular top-flight fixture, however, as the Belgian was unable to find the net in both the 2014-15 and 2015-16 campaigns, despite playing a full 90 minutes in each game.
Lukaku had better success in the 2013-14 season as he found the net in 3-1 and 3-2 defeats for his side, scoring what proved to be a mere consolation in the second of those matches.
However, the Anderlecht academy product certainly knows how to score important goals against City, with a late header to put Everton 2-1 up in the first leg of the 2015-16 EFL Cup semi-finals, only to fire a blank in the reverse fixture as their opponents turned things around.
