Johnny Sexton: Owen Farrell 'favourite to start somewhere' against All Blacks

Johnny Sexton has admitted he faces a big task to edge ahead of "world class" Owen Farrell and into the British and Irish Lions' number 10 Test jersey.

Head coach Warren Gatland insists the Lions want Sexton, Farrell and Dan Biggar all to chase the fly-half berth, despite the option to deploy Saracens' Farrell at inside centre.
