After Jadon Sancho's success in the Bundesliga, Germany quickly became the hottest destination for young Brits who felt starved of first-team opportunities. One such player is Welshman Rabbi Matondo, who followed Sancho out of Manchester City and landed in Schalke.
Matondo has made his breakthrough to the senior side this season and has caught the eye on a number of occasions, prompting rumours of a high-profile move back to England in the summer.
Here's everything you need to know about the winger.
He Caused a Legal Battle When He Joined Man City
Ever since he joined up with Cardiff City's academy at the age of eight, Matondo has been viewed as a future star. Cardiff felt he could become one of the club's greatest products, so they weren't best pleased when Manchester City lure him away for a nominal fee.
Cardiff were so upset that they started a legal battle against City which left Matondo unable to play for his new side for several months until the case was resolved.
The Bluebirds came out on the losing end as a result of their lower academy status, with City paying just £500,000 to take the youngster off of their hands.
He Rejected England at International Level
Matondo is already a regular international for Wales, but he used to play his international football for England.
He was eligible to play for the Three Lions after being born in Liverpool, and he even had the chance to turn out for DR Congo through his parents, but Matondo was always clear that he wanted to represent Wales.
After moving to Cardiff at a young age, Matondo grew up in the Tremorfa district and quickly became loyal to the Dragons, so making a final decision on his international future didn't exactly take him too long.
He's a Versatile Forward
Matondo made his name as a winger at academy level and is usually billed as such, but that doesn't tell the whole story.
He has played largely as either a striker or a central attacking midfielder at Schalke, and he admitted to the Bundesliga that he is comfortable anywhere across the forward line.
Matondo even added that he'd drop back into central midfield if he was asked to do so, such is his desire to play first-team football.
He Grew Up as an Arsenal Fan
He might have been born in Liverpool and represented Manchester City, but Matondo actually spent his youth as an Arsenal fan.
Thierry Henry Is His Idol
Watching Gnabry was all well and good, but Matondo's favourite hobby was watching Gunners legend Thierry Henry in action.
Basically, Matondo likes dynamic, exciting attacking players, so it should come as no surprise that he has turned into one himself.
He Used to Be Man City's Fastest Player
If you watch Matondo play, one of the first things that stands out is his electric pace. The youngster is really, really fast.
In fact, when he was at Manchester City, he actually finished top of the charts in a speed test, coming ahead of Raheem Sterling and breaking the record set by Leroy Sané.
The German was so incensed that he challenged Matondo to a one-on-one race to try and salvage his pride, only to see the youngster beat him yet again.
He Used to Play Rugby
Dating back to his days at school, Matondo has always been an athlete who is happy to do anything sporty, and former PE teacher Harry Trelawny offered a funny anecdote to Wales Online about Matondo's spot in the rugby team.
"Every week he'd put himself forward to play rugby, but we'd never let him because we knew we had to wrap him up in cotton wool a little bit because of his football," Trelawny said.
"I always remember, when we were playing our inter-form rugby championship, Rabbi was actually in line to play for England under-15s against Mexico a few days later, and he was literally begging us to play.
"A man went down and he ran on without us looking, made a 40-yard run and was on the end of massive tackle at the end of it. He got up with a smile on his face. That was how he was."
Man City Have a Buy-Back Clause
After losing Sancho with nothing more than first refusal on any future transfer, City made sure not to make the same mistake when they sold Matondo in January 2019.
After a few weeks of uncertainty, Bild settled on the existence of a €55m buy-back clause, although other reports have that figure at slightly closer to the €70m mark.
Whatever the figure, City have the option to bring Matondo back in the near future, or they could simply choose to re-sign him and flip him for a profit if any team is willing to spend heavily on him. The possibilities are endless.
