SAINTS coach Justin Holbrook has explained his choice of bench for Friday's last Friday's semi-final win - and has given an indication on how they could line up at Old Trafford.

Holbrook plumped for young hooker Aaron Smith on the bench last week, replacing James Bentley who had held that spot in previous weeks and in preference to the experienced back row Joseph Paulo.

He explained that Smith was needed as cover as skipper James Roby was not considered fully fit.

He said: "It all depends on Robes. He went in the game not 100 per cent last time and so we had to carry a specialist hooker on the bench.

“We will just have to see how he travels next week, but if he is still not 100 per cent we’ll probably keep Az there.

"If Robes is fully fit then Joseph Paulo and James Bentley could battle out for the last bench spot. That will be our only change if there is any at all,” he said.
