Marcus Rashford, on the other hand, has been a revelation at Barcelona. The 27-year-old had a slow start to the season, but he's since bagged three goals and five assists for the La Liga holders. His arrival was met with some skepticism, but he's quickly proven his doubters wrong. Rashford is averaging a goal or assist every 88 minutes, and he's back in contention for a place at next year's World Cup.

Alejandro Garnacho has also been adapting well to his new home at Chelsea. The Argentine winger was signed for £40 million and has been a bit of a mystery so far. However, he's shown glimpses of magic, particularly in his substitute appearance against Brentford. Garnacho played a crucial role in Chelsea's second goal but lost his man for the home side's equalizer. He's still raw, but there are signs that Chelsea may have signed one of the league's most exciting young players.

Jadon Sancho, however, remains a bit of an enigma. The 25-year-old had opportunities to revive his career in Italy, but he chose to join Aston Villa on a loan deal instead. He's made just three appearances for his new club, with only eight of his 114 minutes coming in the Premier League. Sancho is still without a goal or assist, and it's unclear whether he'll ever live up to the early hype surrounding him.

Rasmus Hojlund, on the other hand, has found a perfect fit at Napoli. The 22-year-old was often characterized as a target man during his time at Manchester United, but he's thriving under Antonio Conte's system. Hojlund is getting the kind of service he needs, and he's responded with four goals from his first six games for Napoli. He's also starred for his country, scoring a brace and providing an assist in a recent international match.

Finally, Andre Onana has joined Trabzonspor on a loan deal. The 29-year-old was released by Manchester United after the arrival of Senne Lammens from Royal Antwerp. Onana is earning more money at Trabzonspor than he was at United, and he's showing glimpses of his potential. However, he's still inconsistent, and it's unclear whether he'll ever become a top goalkeeper again.
