Brian O'Driscoll and Jonathan Sexton training ahead of the 2011 Rugby World Cup

Brian O’Driscoll can understand why Johnny Sexton was overlooked by the British & Irish Lions but the Ireland legend believes his former team-mate may have suffered for the lack of a man in his corner during Warren Gatland’s final selection meeting.

Leinster and Ireland captain Sexton, 35, was one of the surprise omissions from Gatland’s 37-man squad named on Thursday to tour South Africa and play the world champion Springboks this over three Tests this summer, the head coach preferring Scotland’s Finn Russell to compete with Dan Biggar of Wales and England’s Owen Farrell for the famous red number 10 jersey.
