Italy beat England on Sunday to win their second European Championship.

The two countries could now also be rivals to host the World Cup, which is held every four years after British Prime Minister Boris Johnson backed plans for a bid by the United Kingdom and Ireland for the 2030 finals.

"We will evaluate an Italy candidacy for the 2028 European Championship and the World Cup of 2030, in which the centenary of the world championship is celebrated," Italian Football Federation (FIGC) president Gabriele Gravina said.

"Let's try for the Euros first, then we'll think about the other one."

Some Italian stadiums have not been updated since the 1990 World Cup, the last major soccer tournament hosted by Italy alone.

"We must improve the conditions of the stadiums because if we do not start an investment path in infrastructure we will never be able to aspire to organise such a great event," Gravina said.

"We must do things quickly. For me, we cannot go into a bid thinking that 'we have the stadiums, but if you give me the event, I will then improve them'. That's not how it works."

Other countries that have expressed an interest in hosting the 2030 World Cup include Spain and Portugal.

Argentina, Uruguay, Chile and Paraguay have announced they will make a four-way bid, and Bulgaria, Greece, Serbia and Romania have said they are planning a joint bid.

The bidding process formally starts in 2022 with world soccer governing body FIFA to choose the hosts in 2024.
