Manchester United must do things the hard way if they are to lift the FA Cup for a record-equalling 13th time as they face holders Chelsea for a place in the quarter-finals.
The Red Devils were beaten by Monday's opponents in last season's final and have won just two of their last 22 away games in this fixture when taking all competitions into account.
Defeat to Paris Saint-Germain in midweek halted United's momentum following a superb run of form under Ole Gunnar Solskjaer, and they must also contend with injuries to attacking duo Jesse Lingard and Anthony Martial.
Solskjaer is expected to turn to Romelu Lukaku in the absence of those two players, so with that in mind Sports Mole looks at the Belgian striker's goalscoring return against his former club.
Lukaku was ineligible to play against Chelsea for West Bromwich Albion and Everton during his loan spells with those clubs, but he has still faced the Blues 11 times since leaving on a permanent basis - first to the Toffees then to United - in 2014.
The 25-year-old took eight attempts before scoring against his ex-employers in the Premier League, doing so in United's 2-1 win at Old Trafford last season to level up the match before Lingard struck the winner.
Normal service was resumed earlier this campaign when Lukaku fired a blank in the 2-2 draw at Stamford Bridge, though, coming in the midst of a 12-game scoreless run in all competitions.
However, Lukaku did score both goals against Chelsea in Everton's 2-0 FA Cup quarter-final win in 2015-16, perhaps suggesting that he saves his best for the cup matches.
