Nadal was hired by Auger-Aliassime as an advisor and secondary coach last year and since then he's been working with Felix to improve both his tennis and mindset. It's hard to argue that it doesn't work as the Canadian was able to finally win a trophy and score some major wins on the Tour.
The Spanish coach took to Instagram to congraulate Felix writing:
2022 ATP Most Improved Player of the Year nominees including Alcaraz, Draper, Musetti, Nakashima and Cressy
"Congratulations @felixaliassime for your contribution to the first Davis Cup for Canada. And congratulations for an amazing year that led you to the ATP Nitto Finals in Torino last week. It is a pleasure to collaborate with you and your team."
