Gabriel Jesus is having a medical at Arsenal before a £45m move from Manchester City.
The 25-year-old Brazil forward has been wanted by a number of clubs, both in the Premier League and in Europe, but has opted to join the Gunners.
Jesus has made 236 appearances and scored 95 goals for City since moving from Palmeiras in January 2017.
He has won four Premier League titles during his time at Etihad Stadium, plus three League Cups and the FA Cup.
His playing time next season was likely to be limited after City signed Norway forward Erling Haaland from Borussia Dortmund.
