Ozil, Ox give Bieber an Arsenal tour

As the common football adage goes, "Sing when you're winning."

In the case of Arsenal's table-topping duo of Mesut Ozil and Alex Oxlade-Chamberlain, they've wisely outsourced the chanting and crooning duties in enlisting the help of Canadian pop star Justin Bieber.

Bieber was in London during the UK leg of his world tour, and while in the capital's north end, visited Arsenal's Colney training ground and posed for photos.

Bieber and birthday boy Ozil swapped shirts and struck a pose half as tough as the one featuring the soloist and pacey winger Oxlade-Chamberlain.

By chance, Bieber and Ozil's paths would cross again later that night as the German World Cup champion and Grammy winner were both at Tape Nightclub in London.

Must be nice.
