After the transition from Sporting to the Premier League club, the 27-year-old was met with a personal letter from team captain Martin Ødegaard. A gesture that quickly got a cheeky response.
The letter from Ødegaard, which was also read out in the video, offered an open hand and high expectations for the season.
"If there's anything you need or if I can help in any way, just let me know. I look forward to working together and sharing successes this season".
Gyökeres laughed and countered directly:
Some assists, thanks. That would be nice.
Shortly after his presentation in London, the Swedish national team player sat on a plane to Asia, where Arsenal is underway with their preseason tour.
There, the Swede is expected to make his debut as early as tomorrow with a special jersey number, 14, the same number that legend Thierry Henry wore for the club.
I am convinced that he (Gyökeres) can live up to his new jersey number. I use the word convinced because it's the first thing I became when I talked to him. He is very determined about how he will act and conduct himself in the club, says Arsenal's coach Mikel Arteta at a press conference during the tour.
