However, Masi, who picked up the man of the match award at the weekend, believes that England have the edge over the Welsh.
"It's going to be a tough game but I think England are a bit more dangerous than Wales," said Masi.
"We were quite happy to compete against England and this was a very good performance by Italy.
"We came from two poor games and today we played better rugby, more aggressive and much more physical."
Italy battle Ireland in their last match of the tournament.
