Monaco showed that their first-leg goalscoring antics against Manchester City were no fluke, putting another three goals past Pep Guardiola's side to advance to the quarter-finals of the Champions League.
With Leonardo Jardim's side flourishing, those watching from home
paid them their dues throughout started plotting which of their players they could coax away from Stade Louis II.
And, while Arsenal fans decided scout Gilles Grimandi was there
to watch goalscorer Kylian Mbappé, Manchester United fans had their eyes set on another member of the Monaco starting XI.

Fabinho had been linked with the Red Devils over the summer, so much so that the vacant number two shirt was seen by some as a sign that he was all but a United player.
The all-action Brazilian can play at right-back or in the centre of midfield, from where he popped up with the goal which looked for a long time like it would prove decisive.
While Leroy Sané responded to Fabinho's strike to give City the upper hand, that advantage lasted only a few minutes, with a late header from Tiemoué Bakayoko sending the Ligue 1 team into the last eight.
But by then we'd already seen plenty of this sort of thing.

But wait, we hear you say. They're Manchester United, why do they have to stop at one Monaco player?
And we're not even counting Anthony Martial, who arrived from the principality in 2015.

In fact, do they even have to stop at two?
