If there is any player that was so talked about in the transfer window who ended up staying in their current club, then it has to be Cody Gakpo.
The flying Dutchman was courted by some of Europe's finest, especially Manchester United, but somehow PSV Eindhoven still managed to retain his services for the 2022/2023 season.
Gakpo has been firing on all cylinders so far, and his stats don't lie
Cody Gakpo this season:

13 appearances

13 starts

12.4 90s (1,123 minutes)

9 goals

9 assists

62:23 minutes per goal involvement.

Fantastic performances this season. With the World Cup around the corner, Gakpo will surely have a lot of suitors on his tail
