This month in My London, Lawrence Pollard delves underground to see the capital from a different perspective.
He travels the tube with Tottenham and Cameroon defender Benoit Assou-Ekotto, who proves himself an unusual Premiership footballer.
He goes down the city's sewers with the help of Sir Peter Bazalgette, the great, great grandson of Sir Joseph Bazalgette, the Victorian engineer who built them.
And he's given a guided tour from Viv Askeland, who's lived rough under bridges and in stairwells in a bid to hide herself and stay safe in the big city.
