Most teams are set to return for pre-season training at the start of July as they prepare to play their first friendly matches ahead of the 2021/22 campaign.
Sunderland will play their first pre-season match against Spennymoor Town on Saturday, July 3, when the Euros has reached the quarter-final stage.
The Black Cats will hope they have resolved some contract issues by then, after Aiden McGeady, Charlie Wyke, Luke O’Nien and Denver Hume were all offered new deals but are yet to put pen to paper.
While most players playing at the Euros will be out of Sunderland’s price range, there are some names which could interest the Black Cats.
Here are a couple of players from the tournament who the Wearsiders could target in the coming weeks.
5. Martin Koscelnik - Slovakia
Despite Slovakia's negative approach during a 1-0 defeat by Sweden, Koscelnik is an attacking right-back who can deliver some threatening crosses. The 26-year-old, who plays for Czech side FC Slovan Liberec, is third in the entire tournament when it comes to crosses delivered and has the fifth highest accuracy.

6. Darko Velkovski - North Macedonia
It's fair to say that North Macedonia went out with a bit of a whimper as they lost all three group games. Still, 26-year-old Velkovski should come away with some credit. The centre-back, who plays for Croatian side HNK Rijeka, is ranked in the top 20 when it comes to defensive duels won. His team had plenty of defending to do.

7. Kevin Nisbet - Scotland
Sunderland were linked with the Hibernian striker in January and the 24-year-old ended the season with 12 league goals in 30 SPL appearances. Nisbet hasn't been a starter for Scotland at the Euros, with Che Adams and Lyndon Dykes ahead of him, but has been an option off the bench.

8. Kenan Karaman - Turkey
While Turkey failed to deliver at Euro 2020. Karaman, who usually operates as a striker, showed his versatility after starting his side's first two games on the flank, where he was asked to provide defensive cover. The 27-year-old, who likes to run at defenders and is a threat in the air, will be a free agent this summer after his contract at German side Fortuna Düsseldorf expired.
