Well, it's finally happened. Gylfi's gone. Sigurdsson's transfer was an inevitability that has undoubtedly broken the hearts of every Swansea fan - and it really does hurt seeing him in the blue of Everton.
However, there are 45 million bright sides to this move which will surely help the grieving process. Now, Swansea are a team known for being quite frugal - unwilling to spend big, instead making smart moves with little cost. The reality is that the Swans will reinvest similarly to this expectation - but that makes for a very boring article when discussing replacements.
Here's seven (slightly) unrealistic players that Swansea could replace Sigurdsson with given the fact that they now have a filthy amount of money to spend.
7. Hakim Ziyech
Any avid Football Manager fanatic will be well aware of who this man is - but to many, he's rather unknown. Hakim Ziyech is that little bit of flair that everyone wants in their number 10, and unlike Sigurdsson, he's a wizard in open play.
Having created 101 chances for Ajax last season, racking up 11 assists and managing seven goals, Ziyech seems to be a bit of monster in attack in the Eredivisie, and at 24, he's still got a lot to offer.
Though probably the most realistic target in this list - would he swap Ajax for Swansea? Who knows? The Premier League is a big pull factor, and South Wales would (rather reluctantly from a Swansea point of view) provide a brilliant stepping stone to make it to the top.
6. Jonathan Viera
Here's the thing with Viera. He's almost been entirely ruled out because of a €30m release clause - but the Swans are believed to be happy to spend £25m on Nacer Chadli? It's a frustrating fact seeing as he would be perfect for the club, and the only player to create more chances in La Liga than Viera last season was Lionel Messi.
Don't know who he is? Picture Santi Cazorla with a bit more pace. That's Jonathan Viera. The man made waves in Spain last season and is a technical animal. At 27-years-old, it may be a good time to ply his trade in the Premier League.
5. Samir Nasri
Yes, you're reading that correctly. Other than the fact that he's spent the last six years sitting on the bench at the Etihad Stadium (apart from last season's questionable loan spell with Sevilla), the arrogant Nasri would be a dressing room nightmare and would surely find a way to get under the skin of the entirety of South Wales.
However, his playing days at Arsenal showed he has obvious talent that hasn't been seen in Manchester, and he may well have a bit of juice left in him - despite his trip to the 'Drip Doctors' last Christmas.
His £170,000 wages may not go down too well either.
4. Jack Wilshere
At this point in time Wilshere only seems to be a footballer to provide moral support from the sidelines; sick note in one hand and cigarette in the other.
Despite all of his problems - be it that darned glass ankle of his or his nasty smoking habits, Wilshere is talented. Arsenal fans will never forget THAT game against Barcelona, and whenever he's been fit, Wilshere has given glimpses of brilliance.
If Paul Clement could keep the England international away from injury, the Swans would have a brilliant player on their hands, but that's a massive 'if'.
3. Gelson Martins
Here's where things get taken up a notch - the truly unrealistic possibilities that Huw Jenkins could only dream of. Still, it's worth a shout, right?
Gelson Martins. 22-years-old, nine assists and six goals in last season's Primeira Liga. The youngster has been linked with moves to Liverpool, Manchester United and Arsenal this summer, and although he has a release clause of €60m, Sporting CP are in a bit a sticky situation regarding finances - and Swansea could definitely drive that fee down a little.
Capable of playing anywhere in the attacking midfield department - be it central or on the wings, Gelson is known for his pace and dribbling, and showed that off to the world last term when he terrorised Real Madrid's defence in the Champions League.
2. Ante Coric
Ante Coric. The Croatian number ten dubbed 'the next Luka Modric'. the 20-year-old has a seriously hot potential, and was the first player to ever pass Bayern Munich's youth grading system with the most possible points.
He plies his trade at Dinamo Zagreb and has spent the last two years being linked with moves to every top European team you can think of.
A natural number ten who can dribble and create something out of nothing. Unrivalled vision and just as much ability to pick out the pass. At such a young age Coric has a massive future - and the Swans could tap into that with the £45m. In a few years that number could easily double given today's market.
A risky investment, but a huge gamble that could definitely pay off.
Perhaps less unrealistic than most would immediately assume.
Suso has unfinished business in England (or rather the United Kingdom - seeing as he'd be living in Wales). A troublesome time at Liverpool led to the Spaniard making his way to Serie A, where he has reignited a stalling career with AC Milan.
While he is believed to be happy at San Siro, and it's unlikely he'd want to switch Milan for Swansea; he'd be valued massively and Swansea may even be able to up his wages with the extra Gylfi cash.
Usually deployed on the right wing, Suso lacks the pace of a typical winger and could be very effective in behind the striker - with good dribbling and devastating passing ability.
If there is one unrealistically realistic player Swansea should sign, it's Suso. And the fans would go nuts for the reported Spurs target.
