St Helens head coach Justin Holbrook heaped praise on his outstanding fullback Ben Barba after the 2012 Dally M Medallist produced a faultless display that inspired his side to a 34-2 victory over Salford.

Barba was in sensational form for the Saints as he scorched over for two well-taken tries and had a hand in two others to send the Red Devils home tryless.

The 28-year-old grabbed the game by the scruff of the neck after 25 minutes of anaemic rugby league from Holbrook's side.

When he chimed in to dab a perfectly weighted kick to Tommy Makinson for Saints' first try, the home side began to get the blood pumping.
