Alexis Sanchez's importance to Arsenal was emphasised by his late strike against Paris Saint-Germain on Tuesday night.
In a game where the Gunners needed a moment of magic to level the scores, up stepped their Chilean star to lash home a strike from inside the penalty area.
It's Sanchez's ability to create something out of nothing that makes him so indispensable.

Arsene Wenger certainly recognises that fact, so much so that he's desperate to tie the winger down to a new contract.
Sanchez's current deal expires in under two years and Arsenal must act fast if they're to ensure his future remains at the Emirates Stadium.
And he's reportedly interested in putting pen to paper - but on two conditions.
According to the Mirror, Sanchez not only wants a pay rise on his current £130,000-per-week wages, but a release clause to be inserted.
While the first condition is perfectly understandable, the second will raise some eyebrows.
Clearly, Sanchez is keen to have an escape route in place should he want to leave Arsenal and if he's offered a better deal elsewhere.
His terms won't come as much of a surprise to fans, though, given how Wenger reportedly found the 27-year-old difficult to manage at times last season.
Sanchez has a tendency to throw strops when he isn't played, even when a rest is needed following an international break.
Nevertheless, Wenger will hope to resolve the winger's future as soon as possible after claiming he can be Arsenal's Luis Suarez this season.
He said last month, per Sky Sports: "He has similar qualities [to Suarez] and he has a good timing to run behind the defenders.
"On the flanks he uses a lot of energy by chasing back and I would like to use his energy sometimes a bit more efficiently by going behind the defenders as he is a good finisher.
"He has played centre forward at Barcelona. He is technically top."
A new deal for Mesut Ozil, whose contract expires in 2018, is also said to be in the pipeline.
It's believed the German is willing to extend his stay in north London, with countryman Shkodran Mustafi's £35 million arrival over the summer playing a key role in that.
