Bryan Redpath has warned his club team-mate Jason Robinson is in the kind of form which could continue Scotland's Twickenham misery.
The Sale Sharks player proved to be the Scots' nemesis in the Calcutta Cup clash last year when his try double from full-back helped England to a record 29-3 victory at Murrayfield.
Although the lightning-quick former rugby league player, left out last weekend against Italy, will face Ian McGeechan's side from the wing on Saturday, his Sale club-mate Redpath knows he will have to be watched like a hawk if Scotland are to have any chance of laying to rest their 20-year London hoodoo.
He said: "Jason's a player I'd have on the team-sheet every single week. He's an outstanding player, an outstanding talent and he showed that last week for the club - I think it's a dangerous thing to doubt someone like him.
"He's dangerous in broken play and when he gets the ball one-on-one. He has the ability to beat players in small areas. Wherever he plays in the back three he'll always be a threat. They have got Josh Lewsey at 15 and Ben Cohen back in so it's a very dangerous back three, so it's going to be tough.
"Jason's still only a young guy. He's a nice man, with a good bubbly character that a lot of people will never see.
"He has an ability to beat people, he's got great acceleration and he's exceptionally strong for someone who is not a big, bulky guy. He's an exceptional player and England have a lot of good players, so there's a lot of danger there, but Jason is a threat whenever he gets the ball in his hands."
