WILL Greenwood believes Saturday's Sixways showdown is a must-win game for Harlequins.

Quins and Worcester Warriors have lost their opening four matches and are three points adrift at the foot of the Zurich Premiership table.

"It's a huge game for both sides," said the Quins centre.

"Worcester are very similar to us. They are full of endeavour and graft but they are lacking a bit of patience, cunning, guile and tries. They have also had a couple of performances where they've got lost in tight games and they've had a performance where they've been hammered. But then so have we."
