Manchester United travel to the Cardiff City Stadium on Sunday desperate to keep their Premier League winning run going.
David Moyes has steered the Red Devils to three straight league wins as the champions have marched back into title contention.
However, the United boss has a problem as he looks to select his side for this weekend. The Red Devils are without key midfielder Michael Carrick, who faces a lengthy spell on the sidelines and Moyes is also without versatile star Phil Jones, who has been used in the middle of the park of late and is also out with injury.
And with United struggling in midfield, they are in desperate need of someone to stand up and be counted. That man could be Marouane Fellaini. The £27.5 purchase from Everton has yet to really take off at the Theatre of Dreams, with many questioning his contributions to the team.
When given the chance to shine, Fellani's struggled to inspire those around him and hasn't looked the part alongside Michael Carrick.
Of late, Moyes has put Tom Cleverley and Jones ahead of him, with Carrick as his No.1 choice. But with no Carrick, or Jones, Moyes is left with no option but to make Fellaini a central figure in his starting XI.
And despite major questions being asked of the Belgian, this weekend could be the time Fellaini steps up. As Cardiff look to make it a tricky atmosphere for the Red Devils players and try to bully the United team, Fellaini can finally start paying off his price tag with a solid performance.
The Welsh outfit have already beaten Manchester United's local rivals Manchester City at home this season and on that occasion they scored from two set pieces. In Cardiff's clash with rivals Swansea, the Premier League new-boys once again struck from a set-piece.
With Fellaini in the side, his presence alone will make it harder for Cardiff to hit United from dead-ball situations. The Belgian star will also prove a threat at the other end and could even come away with his first goal for the champions on Sunday.
But don't get me wrong, it's not only Fellaini's presence from set pieces that can benefit United. He has had time to settle at the Theatre of Dreams now and must now prove his sharpness for Moyes' side.
Fellaini is at his best when he takes a game by the scruff of its neck and battles his way past and even through his opponents. Manchester United fans will certainly remember the opening day of last season when the Belgian dominated the Red Devils as Moyes' then Everton team beat United 1-0 at Goodison Park.
The 25-year-old is in need of a big-match performance and this weekend's clash with Cardiff could be the making of the towering midfielder.
