Netherlands
Odds: 12-1
Previous best: Winners 1988
Prospects: The stars of the 2019 Ajax side have struggled since leaving Amsterdam and Virgil van Dijk will be a huge miss. No longer look like potential winners.
Manager: The Dutch have failed to kick on under Frank de Boer after he replaced Ronald Koeman following his departure to Barcelona last summer.
Key player: With no Van Dijk, Matthijs de Ligt will have to shoulder much of the defensive burden.
Austria
Odds: 80-1
Previous best: Group stage 2008
Prospects: Austria haven't reached the knockout stages of a major international tournament since the 1954 World Cup – they've got a good chance of doing so here.
Manager: Franco Foda took over in 2018 and emulated his predecessor Marcell Koller by securing qualification for the Euros behind Poland.
Key player: David Alaba is still only 28 and his impending switch to Real Madrid is a testament to his standing in Europe.
Ukraine
Odds: 80-1
Previous best: Group stage 2012 and 2016
Prospects: Ukraine were a surprise package in qualification, finishing ahead of Portugal, but recent results suggest that momentum has stalled.
Manager: His country's top scorer, Andriy Shevchenko can only add to his legend by navigating a route into the knockout stages.
Key player: Andriy Yarmolenko has struggled at West Ham this season but remains a talisman at international level.
North Macedonia
Odds: 500-1
Previous best: First appearance.
Prospects: North Macedonia made the world stop and take notice recently, as they stunned Germany in the 2022 World Cup qualifiers with a 2-1 win in Duisburg.
Manager: Igor Angelovski has the proud tag of being the first manager to steer North Macedonia to a major tournament – they beat Belarus and Georgia in the playoffs.
Key player: A veteran of Jose Mourinho's Internazionale, Gordan Pandev is still his nation's heartbeat a decade later and aged 37.
