International football gets underway in Europe for the first time in 2025 as the Nations League moves into the quarter-finals stage and the continent's 2026 World Cup qualifying campaign gets underway.

Nations League promotion/relegation play-offs are also on the cards in a week where all the European big guns are in action.

AFP Sport looks at five talking points ahead of the action:

Spain title defence gets serious

Spain face the Netherlands on Thursday in the Nations League quarter-final, with Luis de la Fuente's side looking to win their third-straight title after success in the 2023 edition of the competition and their stunning European Championship victory last year.

Euro 2024 break-out stars Lamine Yamal and Nico Williams, as well as Dani Olmo and Alvaro Morata are in the squad which will play a two-legged tie against the Dutch with a semi-final berth awaiting the winners.

Denmark take on Portugal and France face Croatia in the last eight as well for this first edition of the expanded Nations League final phase.

Battle of the hosts

Germany and Italy clash in the other quarter-final, with the winner not only advancing to the last four but also confirming their status as hosts of the Nations League finals.

Germany travel to Euro 2020 winners Italy for the first leg at Milan's San Siro on Thursday, before the reverse fixture takes place three days later in the Westfalenstadion in Dortmund.

The four-team final tournament begins with the semi-finals on June 4-5. The final is scheduled for June 8.

Tuchel debut

England begin their journey to reach the 2026 World Cup with a new manager at the helm following the appointment of former Bayern Munich, Paris Saint-Germain and Chelsea boss Thomas Tuchel.

The German will be under no illusions that his reign will ultimately be judged by success in major tournaments as England seek to win their first silverware since the 1966 World Cup.

"Exciting and a bit surreal," Tuchel said last Friday of becoming the first German to lead England.

"It's a big honour and I'm very proud of it. I'm very well aware of it, I will make sure that I earn my rights to be in this place."

Tuchel will make his debut next Friday when Albania travel to Wembley, before Latvia visit London on March 24.

Start of the end for Deschamps

One coach whose achievements Tuchel will doubtless be desperate to replicate is outgoing France coach Didier Deschamps, who announced in January he would be stepping down from his role after the 2026 World Cup in North America.

The captain of France's first World Cup-winning side in 1998 took over as coach in 2012 and masterminded his country's second triumph in football's biggest tournament six years later.

"All good things come to an end, and you also need to know when to stop," Deschamps said in January.

"It has been 12 years, and it will have been 14, which is fine. I have done my time, and I still have time left."

Fittingly, Deschamps will begin the end of his reign as France boss against Croatia in the Nations League quarter-finals- the same side he defeated in the 2018 World Cup final.

Courtois returns from the wilderness

Real Madrid's Thibaut Courtois was included in the Belgium squad on Friday for the first time since going into self-imposed exile following a dispute with then-coach Domenico Tedesco in summer 2023.

But following the appointment of Rudi Garcia as Belgium's boss in January, the 32-year-old opened himself up to a return from the international wilderness.

Ahead of Courtois' inclusion, Koen Casteels- Belgium's No 1 in his absence- announced he was "no longer available for the national team" and stated that other squad members were also not best pleased with the Madrid man's expected return.

Belgium will defend its place in League A in a two-legged tie against Ukraine.
