The Azzurri opened their World Cup with victory over England.
"So far, the game between England and Italy has been the best of Brazil 2014, a real game," Mou said in his column for Yahoo.
"It is right to say it was a great victory for Italy, but I have seen the best England in recent years competing at this level.
"It was a very complete game and the teams have played well - tactically, Italy have done very well.
"But, I also liked the philosophy of play from England.
"If it had ended 2-2 it would have been an adequate outcome, but after it went to 2-1, Prandelli has done very well.
"He inserted Thiago Motta in with Pirlo and De Rossi and closed all the spaces. Italy had great maturity, I liked it."
