Andy Farrell pushed towards England - Saracens' McCall
Saracens director of rugby Mark McCall says Andy Farrell initially rejected a role with England, but changed his mind after talking to his club.
The Rugby Football Union named Saracens first-team coach Farrell as part of Stuart Lancaster's temporary coaching staff on Thursday.
"Andy's initial reaction was 'no', because of his commitment to Saracens," McCall told BBC Three Counties Radio.
"Our reaction was the opposite. We kind of pushed him into it a little bit."
Farrell, who was capped for England in both codes of the game as a player, was promoted from Saracens backs coach to first-team coach in 2010 and helped the north London club to last season's Premiership title.
He will miss four league fixtures while on duty with England during the Six Nations.
"We decided this was a unique, one-off opportunity and it would be a brilliant thing for Andy Farrell," McCall added. "As a club we supported him 100%.
"He wasn't reluctant because of a lack of confidence, but because of his loyalty to Saracens.
"Once he realised, as a club, we were supportive of him getting that experience it was a no-brainer.
"I've worked with a lot of coaches over the last 13 years. He's up there with the best of them.
"He's got a passion. He's a born winner. The players here enjoy working with him and I'm sure the England players will think the same."
