Harlequins Director of Rugby Conor O'Shea believes Nick Easter should be England's number eight, regardless of his age.
O'Shea called on England coach Stuart Lancaster to recall Easter after the 34-year-old led the Premiership champions to a 22-9 win away to Leicester on Saturday.
Victory, in a repeat of last season's final, left the Londoners on top of the table with four wins in as many matches.
It was also the first time Leicester had lost at home since Quins stormed the Welford Road fortress in October.
Experienced number eight Easter, who hasn't played for England since winning his 47th cap in the World Cup quarter-final defeat to France last year, led the way as Lancaster watched from the stands.
Lancaster has been looking to blood a new generation of internationals but former Ireland full-back O'Shea insisted Easter still had plenty to offer heading into this November's international programme.
"To me he is the best number eight in England," said O'Shea.
"I don't care whether you are 19 or 34, if you are the best you are the best.
"For the last year he has been playing absolutely unbelievable rugby for us, and long may that continue. And it will because he has got the bit between his teeth. I thought he was magnificent tonight, taking the fight to them.
"I don't want to comment on other number eights, all I know is what we see and what we have in Nick.
"He drives the group, he is incredibly ambitious and proud. He has not written off his international career.
"(New Zealand's) Brad Thorn was older than he was playing in and winning the last World Cup. If he (Easter) can keep himself in shape and plays the rugby he does, he will knock his way back in there."
Quins scored the only try of the match through wing Tom Williams while former All Blacks fly-half Nick Evans kicked four penalties and a conversion, with England scrum-half Danny Care adding a drop-goal.
"Any time you come to Leicester and get a win is exceptional, added O'Shea.
"In the first half we showed we were a pretty good rugby side, in the second we showed the heart you need to be a great rugby side.
"It's only four games in 22 and next week we play Saracens but I could not be prouder of the guys because they put the effort in and showed a willingness to play.
"We know we need to be more clinical but it's early doors and we are happy with how we are progressing."
