Conor O'Shea has described Danny Care's performance against Leicester Tigers as "world class".
The scrum-half created a try in the second half for Harlequins, helping the side return to the top of the Aviva Premiership table with a 25-21 win.
Quins' director of rugby told Sky Sports News: "Danny Care was world class out there tonight. You're fortunate to be able to watch those types of moments.
"From [England head coach] Stuart Lancaster's point of view, he must be thinking, 'I've got [Leicester's] Ben Youngs and Danny Care, how lucky am I?'
"I'm always going to back my own player and Danny's outstanding. From Stuart Lancaster's point of view, there are two Lions-standard scrum-halves competing. I think England are lucky to be in a position like that."
Care has been named as a replacement in England two matches so far in this year's Six Nations tournament.
