Guscott has been left impressed by Wales in the Six Nations
Jeremy Guscott believes Wales are good enough to secure back-to-back Grand Slams for the first time in 100 years.
The former Bath, England and Lions centre described some of the rugby Warren Gatland's men have played in the Six Nations as "awesome".
But he added that winning ugly, as they had to in parts in the 23-15 win over England on Saturday, was the key.
"That's the mark of a very good side and Wales are capable of doing that at the moment," Guscott told Scrum V.
"The rugby they played against Scotland was fantastic. The first half, I just fell in love with it. It was awesome.
"This time England knew what they were up against and made the challenge and sometimes you've got to win ugly."
He added: "The English did really well. I think they surprised a lot of people, particularly the Welsh team.
"They had a couple of chances that if they had put away, the game would have been a little bit closer.
"But I think Wales always had that edge."
Wales are joint top of the Six Nations table with Ireland with two wins each, but Ireland lead on points difference.
They next face a stiff test against France away in Paris on Friday, 27 February.
And Wales legend Gareth Edwards says Wales are becoming even more difficult to beat.
"They are making fewer mistakes than they have ever done," he said.
"They used to try and play this sort of fast game and knick the ball and lose it, giving the opposition all kinds of possession and advantage.
"But now they are keeping the ball and although they didn't quite get over the gain line, there was continuity with the ball.
"England weren't getting it and dare I say it, in set pieces the scrum they looked comfortable and the line-out was very comfortable.
"Against someone like England, we don't expect to have that."
