Gabriel Jesus admits Arsenal's players are excited ahead of tonight's Champions League opener.

The Gunners meet PSV Eindhoven to play their first game in the competition for six years.

"Yesterday some of them were joking in the gym and putting on the [Champions League] music," Gabriel Jesus said in his pre-match press conference.

"I think everyone is happy, the club, the players, the fans because it's a long time since we played in this competition. Now Arsenal are back.

"A club like Arsenal cannot stay without playing this competition."
