Johnny Sexton backs 'flash' Finn Russell to produce his best on first Lions start

• Assistant coach says No 10 has matured as a player

• 'He's won a few trophies and carried that form here'

The British & Irish Lions assistant coach Johnny Sexton has insisted that Finn Russell is still "flash" but believes the Scotland playmaker has the temperament to shine on his first Test start for the tourists against Australia on Saturday.

Sexton described Russell as a "media darling" and as "flashy" before he was named as one of Andy Farrell's assistant coaches, making for a potentially awkward reunion with Russell upon his appointment.
