Hysteria ensued when Arsenal fans awoke to news that Barcelona's Alexis Sanchez had sealed a £35 million transfer to the Emirates Stadium in 2014.
Arsene Wenger rewarded fans' patience with a signing they'd all been waiting for following the arrival of Mesut Ozil the summer previous.
Arsenal craved a player of Sanchez's quality on the flank - a quick, skilful and clinical workhorse capable of winning games.

After hitting 16 Premier League goals in his first season the Chilean became an instant fan favourite, racing across the Emirates turf with grace and scoring a collection of beautiful yet important goals for his new club.
He might have gone off the boil in recent times, but there's little doubting just how vital he's been to Arsenal's aspirations since signing. Here's three of his most important strikes thus far.
Arsenal 1 - 0 Besiktas (27/08/15)
An intense 1-0 win over Turkish outfit Besiktas well and truly marked Sanchez's arrival, claiming his first goal for the club by slotting home on the stroke of half-time and securing 10-man Arsenal's place in the Champions League group stages for a 17th consecutive season.
Jack Wilshere picked up the ball on the edge of the box, played a slick one-two with Mesut Ozil and found the Chilean with space to duly convert his first of many goals for the Gunners.
Arsenal 3 - 0 Manchester United (04/10/15)
Wenger's men have stereotypically struggled against rivals United in recent years, but not on this occasion.
Having netted a hat-trick against Leicester City in the previous fixture, Sanchez was on hand once again to provide the goals for his Arsenal teammates.
A series of silky passes led to the 27-year-old's first goal, delicately back-heeling the ball past David de Gea from Ozil's cross, whilst a stunning second from outside of the box crashed into the top-right corner.
It was arguably Arsenal's finest performance with Sanchez at their disposal, epitomising his influence when on song.
Tottenham 2 - 2 Arsenal (05/03/16)
Saturday's north London derby was by far the most important in recent memory, with Tottenham widely regarded as favourites in the build up and genuine contenders for the Premier League title.
And it didn't fail to deliver what fans have come to expect from the rivalry: unpredictable, tense and full of attacking football.
Following Aaron Ramsey's delightful opener, Arsenal looked in control until Francis Coquelin was dismissed for a second bookable offence. Goals from Toby Alderweireld and Harry Kane shortly followed to determine what looked to be a defeat for the Gunners.
But up stepped Sanchez who, having not scored in the league since October, latched onto Hector Bellerin's pass to fire past Hugo Lloris - and just like that, Arsenal were back in the title race.
