The Chilean international made a switch to the Emirates from Barcelona. The 25-year-old had an impressive season with the La Liga giants last season, despite their trophy less campaign.
According to BBC, the North London club paid around £35m for Sanchez’s signature. The Chilean forward trained with his new club teammates for the first team in London as Arsenal prepare to face Benfica and AS Monaco in the Emirates Cup.
