The Bologna attacker is looking forward to the encounter against the Three Lions, and believes the Azzurri will have their work cut out for them against the Group D winners
The 29-year-old attacker has admitted that the Three Lions pose a bigger challenge than Republic of Ireland did in the group stages, but insisted that the Azzurri will be well prepared.
"The England game will be a fantastic match. I think it's a fascinating game between two great nations. It will be an open encounter and an attractive one," Diamanti stated to the official Uefa website.
"It will certainly be a lot harder than the Ireland match, because though [Giovanni] Trapattoni's side are physically strong, England have players with greater technique and experience.
"They have a lot of great players in their side, starting with [Steven] Gerrard, then [Scott] Parker, [Theo] Walcott and [Wayne] Rooney.
"I haven't watched many of their games, apart from the last one, but in the next few days we will do our research. We are working very hard and we're hoping to go all the way. We are putting everything into it as we do every match."
Sunday's game in Kiev kicks off at 20:45CET.
