Özil is currently out of action with a knee injury picked up during Arsenal’s 2-0 loss to Chelsea at the start of October.
The World Cup winner is expected to be sidelined until the new year due to the problem.
But his Germany team-mate Boateng attempted to lift his spirits by posting a birthday photo on Instagram and writing: “Happy Birthday, Mesut! @m10_official #Özil #JB17”
And Arsenal midfielder Alex Oxlade-Chamberlain took to Twitter to send his regards to his team-mate.
The midfielder tweeted: “Happy birthday @MesutOzil1088 …. Get well soon bro.”
