Jeremiah St. Juste
FSV mainz 05 to sporting cp for $10.45 Million

The 25 year old Dutch centerback has been in Germany for the past three seasons following a move from Feyenoord to Mainz in the summer of 2019.
He has made 66 appearances for Die Nullfünfer (The 05ers) but this season he was limited to only eight appearances and just over 600 minutes of gametime as a shoulder injury kept him out of the squad for long stretches of season.
St. Juste has not made a single appearance for the Dutch National Team and with stiff competition from players like Van Dijk, De Ligt, and De Vrij and also the emergence of the young Jurrien Timber the opportunities for St. Juste to succeed seem far off course from where they were when he signed for Mainz.
The Dutchman signs for one of the most prestigious clubs in Portugal in Sporting Club, which has seen the likes of a young Cristiano Ronaldo, Luis Figo and most recently Bruno Fernandes which they all used to achieve great heights in football.
Sporting finished finished 2nd in the Primeira Division and St. Juste will be joining a very talented young side with the likes of Pedro Gonclaves, Matheus Nunes and rising defender Goncalo Inacio all under the age of 23.
Boubacar Kamara
Marseille to Aston Villa for free

Kamara is a product of the Marseille Youth Academy representing both the U19 side and the Marseille B team before making the jump to the first team back in 2017 and has represented the former French giants 170 times, as well as representing the French National side three times.
A Defensive midfielder by trade and that is where he spends most of his time but he can also be deployed in the backline as he can spend some time as a makeshift centerback as well.
Aston Villa is making a shrewd signing in Kamara as he has been valued at well over $30 million and they managed to pry him from the French side for free as his contract expired. He has been a highly touted midfielder as his presence playing deeper has him in the top 25% of all midfielders in the big five leagues for ball retention rates and his ball winning abilities.
Villa has had to stave off teams like Manchester United, Newcastle United and Roma who were all looking for Kamara’s signature, and he should undoubtedly improve Steven Gerrard’s side who finished 14th last season and had a bit of a relegation scare.
With Kamara joining the side and having a full season of Philippe Coutinho for the next season they will be looking for a better improvement this upcoming season.
Brenden Aaronson
RB Salzburg to leeds united for $36 Million

Aaronson is an American Attacking Midfielder who spent the last season with Red Bull Salzburg after joining from the Philadelphia Union of the MLS after tearing up the league and he has only improved since he moved to Austria.
Since arriving from the US, Aaronson has made 66 appearances for the Austrian side and has made quite the impression netting 13 times and being involved in another 15 goals, which has jumped his valuation by nearly $10 million since the start of 2021.
Aaronson has also become a regular starter for the USMNT and he has paid them back netting six times in 21 appearances playing typically in the 10 slot.
He joins a Leeds side that had a pretty miserable 2021/2022 campaign as they narrowly avoided relegation to the Championship courtesy of a 2-1 win on the final day of the season to Brentford. Following the departure of mastermind Marcelo Bielsa midway through the season, Leeds were in a freefall and it took current manager Jesse Marsch everything in his power to keep them afloat.
Aaronson could join the team and potentially make an immediate impact, but with the style of play the Premier League is known for it might take him a little bit to adjust to his new settings, and it wouldn’t come as a surprise if he does stumble out of the gate. With his young age Leeds could look to bank on the American for the future should they secure another season of top flight football.
Matias Olivera
Getafe to Napoli for $12 Million

Olivera is a left-sided fullback by trade and has done so on 110 times for Getafe since his arrival from third division side Albacete Balompie back in 2019 following a season long loan after his arrival from Uruguay.
While he is a defender by trade he can also line up higher up the pitch as a left-sided midfielder, and while his goal contributions isn’t anything eye-popping with one goal and three assists this season the 24 year old will certainly be looking to improve on those numbers in Naples.
With the starting left back berth wide open now as Faouzi Ghoulam set to depart the club and Mario Rui turning 32 this season the need to get younger on the flanks for Napoli is a much needed investment and for only $12 million it could be a low risk move.
Roman Burki
Borussia Dortmund to St. Louis city sc for free

St. Louis CITY SC made one of their first ever signings in snapping up the 31 year old Swiss shot-stopper following the end of his current contract with Borussia Dortmund as he will become one of the marquee players for the side when they begin play during the 2023 MLS season.
Burki has spent the past eight seasons in Germany split between SC Freiburg and Dortmund after leaving the Swiss Super League. He made 268 appearances for the German sides and his most prolific stint came with BVB where he racked up 83 clean sheets in 232 appearances.
Burki was left as a replacement to the new arrival Gregor Kobel and the outgoing Marwin Hits for most of the 2021-2022 season as he was only able to register a single game coming during the final Bundesliga match week as Dortmund’s strong Swiss goalkeeping influence kept Burki out of the squad for almost all of the season.
St. Louis CITY made a huge statement by prying a former top goaltender on a free from one of the largest German clubs, albeit for one who was massively out of favour for his former team, but a step to America might just be what Burki needs to rejuvenate a once promising, but now stagnant career.
While he might not be the youngest player on this list, at only 31 years of age Burki might be able to continue on for another 5-6 years before calling it quits which could be a massive help to the new MLS franchise who will be looking for leaders on and off the pitch as they get their franchise started.
