Roberto Mancini has expressed regret about Italy's failure to secure automatic World Cup qualification and warned the Azzurri must forget about their Euro 2020 success ahead of the playoffs.

Italy, who missed out on the 2018 World Cup, have undergone a transformative period under former Inter and Manchester City manager Mancini. That culminated in them triumphing at Euro 2020 – their first European Championship title since 1968.

The Azzurri embarked on a world-record 37-game unbeaten run, which ended at the hands of Spain in the Nations League semi-finals in October, but their World Cup prospects hang in the balance.

Italy finished runners-up to Switzerland in Group C, as did Portugal to Serbia in Group A. The pair were then drawn on the same play-off path, meaning there is no way that Mancini's side and Cristiano Ronaldo and co can both qualify for Qatar 2022.

Italy have to navigate past North Macedonia in the play-off semi-final in late March and Mancini wishes his side had managed to confirm qualification earlier.

He told Sky Sports Italia: "Yes, but this is football, it is sport. Sometimes you deserve to win and you don't win, we deserved to finish the group much earlier.

"We let ourselves go a bit and now we have to roll up our sleeves and do a great job in the two games. But I remain optimistic, as I knew that our group with Switzerland would be difficult. I thought we would qualify, but I knew it would be difficult."

Reflecting on Euro 2020 success, Mancini said: "We have done an extraordinary thing, we have made millions of people happy. It is the most beautiful thing, of which we are all proud.

"But the European Championship is behind us, now we have to think about something else."

The play-offs are one-leg ties, with Italy and Portugal hosting North Macedonia and Turkey in their respective semi-finals.

The winners of those two semi-finals will meet in a final, in which Portugal or Turkey will be at home, to secure a place at Qatar 2022.

If Italy can negotiate such a tricky route, Mancini believes they have players who will benefit from experiencing a World Cup.

He said: "There are many players who can improve a lot and, for me, it will be important to go to the World Cup because I think there are 10-12 players who can improve a lot going to the World Cup, if we go there."
