BBC Analysis editor Ros Atkins looks at how Qatar won the World Cup, as well as the human rights and environmental issues surrounding the tournament.

There are some familiar names in the Morocco side.

There are two current Premier League players: West Ham's Nayef Aguerd and Chelsea's Hakim Ziyech.

Ex-Wolves defender Romain Saiss and former Southampton winger Sofiane Boufal also make the starting XI.

Keep an eye out for Paris St-Germain full-back Achraf Hakimi too - he's a very exciting talent.

Morocco: Yassine Bounou, Noussair Mazraoui, Nayef Aguerd, Romain Saïss, Achraf Hakimi, Sofyan Amrabat, Azzedine Ounahi, Sofiane Boufal, Selim Amallah, Hakim Ziyech, Youssef En-Nesyri.

Like in the Croatia side.

Chelsea's Mateo Kovacic and Tottenham's Ivan Perisic start, along with former Spurs midfielder Luka Modric and ex-Liverpool defender Dejan Lovren.

Only four of the starting XI played in the 2018 World Cup final defeat by France.

Croatia: Dominik Livakovic, Borna Sosa, Josko Gvardiol, Dejan Lovren, Josip Juranovic, Mateo Kovacic, Marcelo Brozovic, Luka Modric, Ivan Perisic, Andrej Kramaric, Nikola Vlasic.

For years the winner of the Ballon d'Or would be one of two names - Cristiano Ronaldo or Lionel Messi.

But in 2018 that duopoly was ended by Luka Modric. The Real Madrid midfielder was deservedly recognised by taking the prestigious award following a stellar year in which he was also named player of the tournament for the World Cup in Russia.

Modric was instrumental in leading Croatia to the final as they beat England in the last four before losing to France.

Now 37 and likely in his final World Cup, Modric is back hoping to take Croatia one step further.
