Arsene Wenger signed the Switzerland international in a £33m deal from Bundesliga outfit Borussia Monchengladbach on Wednesday afternoon.
Xhaka has put pen to paper on a five-year deal as he becomes Wenger’s first signing of the summer transfer window as Arsenal look to improve their squad.
Djourou, who is a team-mate of Xhaka in the Switzerland squad, spent nine seasons at the Emirates Stadium before he eventually quit in 2014.
And the 29-year-old defender is a big fan of Arsenal’s £33m signing, taking to Twitter to give Gunners supporters an idea of the type of player that Wenger has signed.
