3. Kasper Dolberg
Considered a hot prospect for a number of seasons at Ajax, Dolberg has ultimately struggled to recreate his performance in his debut campaign, when he bagged 23 goals in all competitions.
The striker, still just 21, followed that up with tallies of nine and 12 before joining Patrick Vieira’s Nice this summer for €20.5 million.
4. Oliver Burke
It feels like an awful long time ago that Burke joined RB Leipzig in a record deal for a Scottish player as one of the most hyped young footballers in Europe. A season in Bundesliga was followed by an even more expensive transfer to West Brom, but he has played just 21 times for the Baggies and spent the second half of last season on loan at Celtic.
The 22-year-old has been loaned out again, securing a move to La Liga side Alaves.
5. Neven Subotic
Once a Borussia Dortmund – and Football Manager – hero, Subotic spent the last 18 months at Saint-Etienne after injuries had blighted his final few seasons at the Westfalenstadion stadium. He was heavily involved in France until a knee injury in April ended his season early, and he returned to Germany in the summer to join newly-promoted cult club Union Berlin.
In only his second game at his new club, he was given the opportunity to take on Dortmund and played the full 90 minutes in a shock 3-1 win for Union.
6. Wissam Ben Yedder
Best known in England for coming off the bench at Old Trafford to score twice in four minutes as Sevilla knocked Manchester United out of the Champions League in 2018, Ben Yedder was briefly linked with a move to the Red Devils, only to join PSG in a €40 million deal.
The transfer represented Sevilla’s record sale, while Rony Lopes moved to Spanish outfit as part of the deal.
7. Bas Dost
After scoring a great number of goals for Sporting Lisbon without ever appearing in vogue with the wider footballing world – his three seasons produced 36, 34 and 23 goals in all competitions – Dost has now joined Eintracht Frankfurt, where he will more than likely score even more goals.
8. Renato Sanches
Once considered one of the best young player in Europe while a Benfica player, since winning Euro 2016 with Portugal, Sanches has joined Bayern Munich in a big-money move, where his most notable contribution was getting relegated on loan at Swansea City.
After the first Bundesliga fixture of the season, the 22-year-old made clear his desire to leave Bayern and has got his wish thanks to Lille breaking their record transfer fee to sign the midfielder for €25 million.
9. Shinji Kagawa
Having spent the second half of the season on loan at Besiktas, Kagawa has permanently ended his second spell at Borussia Dortmund by joining Real Zaragoza, where he will play second tier football for the first time since leaving his native Japan almost a decade ago.
10. Gael Kakuta
Given Kakuta has joined Amiens on a permanent deal, the 13th move of his senior career. It prompts people to actually starting to think he really was not worth all the hassle when Chelsea first signed him.
