Mesut Ozil has given former Arsenal team-mate Nicklas Bendtner some advice after the maverick striker moved to Wolfsburg.
Bendtner, 26, has been a free agent since Arsenal decided not to renew his contract at the end of last season.
The Danish striker was announced at the Bundesliga club on Friday afternoon, where he will wear the No 3 shirt.
World Cup winner Ozil took to Twitter to tell Bendtner good luck, but also gave him some advice.
He said: "good luck in Germany @bendtnerb52! Don't do silly things and behave!"
Wolfsburg coach Dieter Hecking, speaking at the player's official presentation, said: "We want to have a good run in all three competitions we are in this season and for that we need players who know these challenges and are used to them."
