Jesus said it was a pleasure to play for Manchester City. Winning 11 trophies has been amazing, and I feel like I am a better player now.
My four premier league titles are very special to me. The manager, my teammates and the fans have supported me over the past 512 years.
Mikel Arteta said he was excited. A player of this stature has been recruited by the club. We all know Gabriel from his time in the premier league and his success here.
"This is a position that has been on our radar for a long time now, and we have been able to get a player that we all wanted, so I'm really happy."
The team missed out on the playoffs and are looking to strengthen.
Pierre-Emerick Aubameyang joined Barcelona for free in January, and Arteta's side were in need of a new forward.
Jesus, who had only one year remaining on his contract at City, contributed 13 goals and 12 assists in all competitions for the premier league champion last season.
He scored 95 goals for City.
