Manchester United have a point to prove against Tottenham this afternoon.
The Red Devils flew out of the blocks this season but questions have been raised over their title credentials since the international break.
A laborious, defensive performance at Liverpool was followed up by a uncomfortable 1-0 win at Benfica and compounded with a shock defeat at the hands of Huddersfield Town. A routine victory at Swansea City in the Carabao Cup has down little to quell concerns.
The situation is no more amplified by the stories that have emerged of Jose Mourinho's behaviour after the Huddersfield loss with the negativity even seeping into training.
The imminent challenge of Tottenham certainly looks a difficult one, too. Spurs looked to have completely eradicated their Wembley hoodoo last week when they took Liverpool to the cleaners in an emphatic 4-1 win.
United will at least be buoyed by the fact Harry Kane has been ruled out of the clash with a hamstring injury - likely prompting Fernando Llorente to deputise as his replacement.
Nevertheless, playing Tottenham at Old Trafford proved something of a turning point last season and Mourinho will hoping for much of the same this year.
The Red Devils were one of just four teams to down Tottenham in the league last season with Henrik Mkhitaryan thrashing home the winner.
Even some of the club's finest ever teams needed a little luck against Tottenham in the past, though.
That was certainly the case in October 2010 when Spurs arrived at Old Trafford as a Champions League outfit for the very first time. The XI they brought that day featured the likes of Gareth Bale, Luka Modric and Rafael van der Vaart.
Ultimately, the Red Devils ran out 2-0 victors with Nemanja Vidic and Luis Nani providing the goals.
You could argue that a certain Mark Clattenburg provided the assist for Nani, mind.
Check out his thoroughly bizarre goal below:
So, what exactly happened?
Tottenham 'keeper Heurelho Gomes had placed the ball down for a free-kick after Nani had handled the ball in the penalty area. Although almost everyone in the Theatre of Dreams had seen the incident, bar the referee.
Nani hadn't been penalised and the Portuguese eventually took the initiative by tapping the ball home as the penny dropped for Gomes.
Play to the whistle and all that, right?
