William Gallas is a rare former footballer who can count three top London clubs on his CV.
Gallas played for both Tottenham and Arsenal although is not held in the same disdain by fans as Sol Campbell, and he also played for Chelsea too.
Gallas played for Chelsea between 2001 and 2006, Arsenal between 2006 and 2010, and Tottenham between 2010 and 2013.
An impossible question? Whoever Gallas picked, he would offend two clubs, but he answered it anyway.
After a big smile, he gave a one-word answer, "Chelsea."
Gallas' time at Chelsea ended under a cloud, with him being sold to Arsenal in part-exchange in with Ashley Cole's move away from the Gunners.
He went on to captain Arsenal, but Chelsea was the only club at which he won a trophy, two Premier League titles and one League Cup.
Are you surprised by Gallas' choice?
