Leonita often posts adoring snaps of the couple on her social media, where she boasts almost 200k Instagram followers.
Xhaka and Leonita have been together since meeting during the midfielder’s time at Bundesliga club Borussia Monchengladbach in 2015.
They were engaged in June 2016 and tied the knot at a ceremony in July 2017.
She was born in Albania and was raised in Pristina, Kosovo. However her family moved to the Ruhr region of Germany as Leonita grew older.
Xhaka has had a mixed spell at the Gunners with his wife previously locking her Instagram account after appalling death threats.
Apart from the pictures on social media, the pair seem to remain quiet over their private lives.
It read: “Happy birthday to the love of my life!
“I’m so happy to have you in my life, as long as I have you by my side I know anything is possible.”
Despite Xhaka’s Arsenal future being up in the air, the midfielder is determined to focus on the European Championships.
He said: “There are always rumours as soon as the transfer market opens but I don’t want to talk about my future.
“I am 100 per cent focused here with the national team and I want to keep that until the end of the tournament.
“What happens afterwards, you will then get to know about it. Everything else doesn’t distract me.
“I am fit and motivated and looking forward to doing a lot of things in this tournament for the team.”
