Gabriel Martinelli has claimed that Arsenal boss Mikel Arteta is an 'unbelievable' coach.
Martinelli was signed from Brazilian side Ituano back in the summer of 2019 and he has since established himself as one of the most promising talents in north London, notching 16 goals and nine assists in 70 outings for the club.
The 20-year-old's goalscoring exploits even earned him the Premier League's player of the month award for December but it hasn't always been plain sailing at the Emirates Stadium.
