And the Chile international was clearly in a good mood on Tuesday morning as he took to social media to post a video of himself singing in his car on his way to Arsenal training.
Sanchez posted the video above on his Instagram account and wrote: “Good morning…”
We’re not sure that videoing himself while driving is the most sensible thing to be doing but at least he seems in good spirits ahead of Arsenal’s clash with Monaco on Wednesday.
The 26-year-old has been in fine form for Arsenal since his £35m transfer to Emirates Stadium from Barcelona last summer.
He has scored 12 goals and made seven assists in the Premier League so far this season and also netted three times in the Champions League group stage.
Arsenal were training ahead of the first leg of their Champions League last-16 clash with Monaco at Emirates Stadium on Wednesday night.
