The 25-year-old striker hasn’t featured for the north London club since a 2-0 victory over Tottenham Hotspur in the FA Cup third round at The Emirates in January.
Walcott was forced to miss England’s World Cup campaign, too, with the Arsenal man likely to have been named in Roy Hodgson’s 23-man squad for the major tournament.
But the former Southampton striker seems to be on track for a return in the new season after taking to Instagram to post a video of his training at Arsenal’s Colney complex.
Walcott scored five goals and made four assists in 14 Premier League appearances last season.
