Tom, who has 53 caps, needed surgery last autumn on a debilitating hip injury that caused him to miss this year’s Six Nations.
He recovered to make the summer tour to Japan and New Zealand where he was a replacement in all three Tests.
But he returned to the Sale team that comprehensively beat the Falcons for his second Premiership game of the season and was at his marauding best.
Ben missed the World Cup last year through a hamstring injury and although he was named in the Six Nations squad, he did not play a single minute.
“They’re a menace, they’re everywhere, they’re like a splat on the game,” said Sanderson.
“Steve Borthwick left them out of camp, so they could prep and play [against Newcastle], which I think was a really smart move. He wanted to see how good they were in form and they were in form.
“I hope Steve has got what he wanted because we certainly have.”
