Conor O'Shea says Danny Care must start for England in Six Nations

Harlequins coach Conor O'Shea says his captain Danny Care should be England's starting scrum-half in the Six Nations.

O'Shea has urged England coach Eddie Jones to look closely at Care, who has been in superb form this season.

Joe Simpson of Wasps is also catching the eye, while the likes of Ben Youngs of Leicester and Saracens' Richard Wigglesworth will also be contenders.

Care, 29, leads Quins for Sunday's trip to Worcester and director of rugby O'Shea insists he is indispensable to the club.

"Danny was brilliant against Gloucester last weekend [in the 39-39 draw]. When the going got tough he really chucked himself into tackles to make the difference," O'Shea said.

"He's such a threat and I would never put a team out without him involved somewhere in the 23.

"Everyone is asking, 'who is Eddie Jones looking at?' Well Danny is an absolutely magnificent rugby player."

Worcester are searching for their third Premiership victory of the season and director of rugby Dean Ryan believes stopping Care will be key to their hopes of springing an upset.

"We've got a unique challenge defensively to cope with Harlequins' speed of thought," Ryan said.

"Danny Care and Nick Evans play with an incredible tempo. The team play with a level of freedom that can catch you by surprise if you assume anything.

"But we're at home and I'd like to think we can put a few things together that can put them under pressure."
