The 18-year-old was promoted to the first team in the absence of the injured Derick Hougaard and Alex Goode but having also impressed against Bath and Gloucester, Henson – who will arrive at the club after his reality television commitments – may have to be accommodated in the Saracens midfield.

And head coach Mark McCall admits he has been impressed by the teenager’s maturity in recent weeks.

He said: “We have got to be careful not to put Owen into too elevated a status.

“But in the last three weeks he's gone to Bath and Gloucester and now here and in all three games he's brought a maturity to all his performances.

“All we said to him is that our pack of forwards need to look back at our No10 and see somebody who is in control - and Owen's been in control in all those games.”

The praise was quickly echoed by Farrell senior who knows full well what his son is going through having burst onto the scene as a 17-year-old with rugby league side Wigan.

And the cross-codes legend is adamant he never doubted that Owen would take to the pressure of professional rugby like a duck to water.

He said: "I know, from watching him all his life, that Owen is ambitious and confident and doesn't struggle with nerves.

"Within five minutes of the start he was exactly where he wanted to be. He seemed in control.

"I want him to play well every week. That's all that matters. Being a professional rugby player is difficult.

"It's a lot of pressure, people's livelihoods are at stake. It's completely different from being one of the best players coming through the age groups.

"Professional rugby is about not making the same mistakes twice. If you've got that temperament you'll have a decent career.

“Potential means nothing if you're not learning.”
