The broadcaster have announced that Chelsea legend and children's' author Frank Lampard has joined the channel for the forthcoming season, following his retirement in February of this year.

But he has been snaffled by BT for the season ahead, to work alongside other erstwhile members of England's Golden Generation: Steven Gerrard, Rio Ferdinand, Michael Owen, Paul Scholes and, er, Owen Hargreaves.
Gerrard welcomed Lampard in self-effacing fashion, attempting to get ahead of the predictable deluge of 'Gerrard and Lampard can't work together' gags.
He posted this on Instagram with the caption:
