Didn't see that coming...

Andy Farrell's decision to quit as head coach of Saracens was something of a bolt from the blue.

Having rejected the chance to join the England coaching set-up full time in April out of apparent loyalty to his club what, pray, has prompted the U-turn?

- a simple change of mind? Unlikey.

- the lure of filthy lucre? Possible.

- a bust up with someone at Sarries? I wonder.
