A hectic, congested year of football culminates in the delayed European Championship, which starts on June 11 when Turkey take on Italy in Rome.

Euro 2020, hosted in 11 cities spread across the continent, was meant to be a celebration of the 60th anniversary of UEFA's international tournament. Instead, the coronavirus pandemic derailed the plans, forcing the postponement of the event until 2021.

Though the qualified teams had been readying themselves to play last year, and the pandemic has forced a much-altered football calendar in 2020-21, some countries may have benefitted from the delay.

For others, it may be a case of what might have been. Here, using Opta data, Stats Perform looks at how the main favourites to go all the way have been boosted by the postponement. 

Belgium

Romelu Lukaku – Belgium's record scorer – has built on a brilliant debut season with Inter, going on to help the Nerazzurri claim the Scudetto, with the 28-year-old netting 24 times in Serie A (a tally bettered only by Cristiano Ronaldo), at an average of one goal per 120 minutes, and providing 11 assists in the process.

Another player who has gone from strength to strength in 2020-21 has been Youri Tielemans, who lashed in an exceptional strike to win Leicester City's first FA Cup. The midfielder racked up 4,438 minutes of playing time, the sixth-highest total in Europe's top five leagues, so Roberto Martinez – whose future is uncertain – may have to manage him carefully.

England

Gareth Southgate named a 33-man provisional squad, and while the England boss does have doubts over the fitness of some key stars, he cannot complain at the wealth of talent at his disposal, with several players having come to the fore in the last year.

John Stones is back to his best, and right-backs Kyle Walker and Kieran Trippier have won titles in England and Spain respectively. Ahead of them, Jude Bellingham – who could become the youngest Three Lions player to appear at the Euros – had an outstanding season with Borussia Dortmund, though it is in attack where Southgate really is spoilt for choice.

Harry Kane won the Premier League golden boot and topped the assist charts, while back-up Dominic Calvert-Lewin registered a top-flight goal every 179.63 minutes. Behind them, Phil Foden and Mason Mount are talismanic figures Champions League finalists City and Chelsea, while Jack Grealish created 81 chances – the third highest in the division – for Aston Villa, despite missing 12 games through injury. 

France

England's options somewhat pale in comparison to the depth Didier Deschamps has to play with. Eduardo Camavinga looked set to be one of the youngsters to break onto the scene for Les Bleus, but the Rennes teenager has not even made the squad for the rearranged tournament, while Anthony Martial is another big name to miss out.

Kylian Mbappe reached last season's Champions League final and has gone on to score 42 goals in 47 appearances across all competitions this term, averaging a strike every 89 minutes, while Antoine Griezmann is looking sharp.

As if it was not enough, Deschamps has also recalled Karim Benzema, who scored 30 goals in all competitions for Real Madrid to earn his first call up in over five years. In midfield, N'Golo Kante has been spectacular for Champions League winners Chelsea, with only six Premier League midfielders who have attempted over 75 tackles recording a higher success rate than his 53.16.

Germany

Joachim Low has decided to call it quits after the tournament, with Hansi Flick incoming. But surely that will only spur Germany on as they look to end Low's tenure on a high, and he has recalled 2014 World Cup winners Thomas Muller and Mats Hummels to help the cause.

With Timo Werner having struggled to convert chances into goals for Chelsea – scoring 12 times in 52 appearances and registering a shot conversion rate of just 7.59 in the Premier League – Muller, who created the most chances (93) and provided the most assists (18) in the Bundesliga – will share the burden, while Jamal Musiala, Bayern Munich's youngest Champions League goalscorer, is surely one of the youngsters to watch.

Italy

After failing to qualify for the 2018 World Cup, Italy were in need of a rebuild, and Roberto Mancini has provided the steady hand required.

Mancini is unbeaten in all 26 games of his Italy tenure, as he closes in on the all-time record of 30 set by Vittorio Pozzo in the 1930, and the Azzurri look well placed to challenge. One question mark could be over goalkeeper Gianluigi Donnarumma, who seems destined for a move to Juventus.

Netherlands

Perhaps no team has undergone more change in the past year than the Netherlands. Ronald Koeman looked set to have a strong side heading into Euro 2020, albeit injuries would have shorn him of Memphis Depay and Donyell Malen.

As luck would have it, both of those attackers will be fit for the Oranje, and come in off the back of strong seasons with Lyon and PSV respectively. But it will not be Koeman who is in charge – he is of course now at the helm at Barcelona, though whether his tenure continues for much longer remains to be seen – with Frank de Boer his replacement.

Portugal

More records tumbled in 2020-21 for Ronaldo, though there is no doubt the 36-year-old's powers are waning slightly with age.

Portugal are, of course, the holders, having seen off France in 2016, but Fernando Santos' squad is arguably much stronger than it was five years ago, with Andre Silva – who finished behind only Robert Lewandowski in the Bundesliga scoring charts this season – providing a focal point up top, while Bruno Fernandes, Diogo Jota and Joao Felix have continued their trajectories of improvement in the last year.

But it is Ruben Dias' form over the last season that may benefit Portugal the most. The centre-back has been imperious for Man City, playing a crucial role in a defence that has conceded just 42 goals in all competitions.

Spain

With Sergio Ramos not judged to be fit, Luis Enrique has picked a relatively inexperienced – at least at international level – defence, with only 24 players named in his squad.

Pau Torres is certainly a player who has improved over the past 12 months. He has just helped Villarreal to a Europa League triumph, with the centre-back, who is sure to be interesting some of Europe's biggest clubs, being the defender with the most games played in the competition without being dribbled past (nine). Spain have also been buoyed by Aymeric Laporte's switch of allegiance from France.

Thiago Alcantara has not always hit his best form at Liverpool, though Spain's midfield is boosted by two title winners in Atletico Madrid duo Koke and Marcos Llorente, who was involved in 23 goals in 2020-21.

Up top, Gerard Moreno netted 30 goals in all competitions for Villarreal – among LaLiga players, only Lionel Messi played a part in more goals.
