Luis Suarez and Arsenal have certainly had some transfer history.
Back in 2013, the Gunners were keen to add Liverpool's star striker to their ranks despite his 10-game ban for biting Chelsea's Branislav Ivanovic.
Arsene Wenger needed a Robin van Persie replacement and the Gunners famously bid £40m and £1 for the Uruguayan - his release clause was said to be £40m.
However, Liverpool stated that it was not the fixed price for Suarez and that they were free to negotiate, wanting around £55m for him.
In the end, Arsenal didn't meet their valuation and Suarez went on to enjoy one of the greatest seasons ever seen in Premier League history, scoring 31 goals.
The whole incident also sparked one of the most infamous football tweets from John W. Henry, who posted: "What do you think they're smoking over there at Emirates?"
Five years later, Suarez is a Barcelona legend and Arsenal have snapped up one of his Uruguayan colleagues in Lucas Torreira.
The defensive midfielder joined from Sampdoria after the World Cup, where he excelled for the South American nation.
And it turns out that Suarez played a vital role in Torreira's decision.
The 22-year-old's agent revealed on Sport890 that Suarez gave a glowing recommendation of Arsenal and it was vital in Torreira's decision.
Who knew Suarez had such a soft spot for the Gunners?
If he'd completed his switch to the Emirates back in 2013, Wenger's final years as manager could have been a whole lot different.
Had he played with Mesut Ozil - who joined right at the end of the 2013 window - Arsenal would have had the best forward line in the Premier League.
Torreira is expected to be an instant starter for Unai Emery's side in 2018/19, with Granit Xhaka likely to be afforded a more advanced role - where he should thrive a lot more.
Arsenal have needed a defensive midfielder since the days of Gilberto Silva and thanks to Suarez, they've got one of the hottest prospects in world football.
