Geordan Murphy believes England will attempt to win the Six Nations Grand Slam while 'playing like Saracens'.
The Irishman is the only member of the current Leicester Tigers squad to have won a coveted Six Nations' clean sweep with his country.
Murphy was part of the Ireland team that won all five matches during the 2009 Six Nations.
And he will be hoping many of his club's team-mates come back from Cardiff tonight in a similar position.
England have won all four of their matches so far but scored just one try in their last three games and developed a 'cup rugby' style that Murphy likened to Aviva Premiership leaders Saracens.
The Fez Heads are renowned for their pragmatic style and are joint ninth in terms of tries scored this season – despite topping the table in points.
"England are playing cup rugby at the minute," said the 34-year-old. "It's Saracens-esque. They are kicking well and defending well and they are going to have to do that against Wales.
"That could be the thing that wins the Grand Slam for them. They will not play expansive rugby because Wales have the edge and experience on them in those areas. They will kick the corners and grind it out and win the battle up front.
"They can win it – but they didn't play a lot of rugby against Italy and that was disappointing because I thought they would put them to the sword.
"The Welsh side are underrated and they are eyeing the English scalp which a lot of other nations have done in previous years to stop an English Grand Slam.
"I am a little bit nervous for the English guys because I think Wales will be well up for it.
"I will be cheering on England because I know lots of guys in the squad.
"But I just want to see some good rugby and I want to see the side that plays the best rugby win.
"The championship is nice to have on your CV but to get your hands on a Grand Slam is great. It should be a good contest."
