Martin targetting U2's top spot

Coldplay frontman Chris Martin's ultimate goal is to surpass U2 as the greatest rock band on the planet - and he is taking inspiration from Sylvester Stallone to help him achieve his aim.

The In My Place rocker put a picture of the I Still Haven't Found What I'm Looking For legends on his studio wall during recording sessions for upcoming album X&Y to push his creativity to unheralded heights.
