Thomas Meunier

Manchester United, Milan and Paris Saint-Germain are among the major European outfits who are due to farewell high-profile players when free agency comes into force on June 30.

Domestic leagues across the world appear increasingly likely to run beyond that deadline, meaning sides up and down the divisions could be forced to renegotiate deals beyond the typical expiry date.

It remains to be seen how governing bodies will approach the unfamiliar territory but Edinson Cavani, Mario Gotze and Zlatan Ibrahimovic will be watching closely like dozens more across Europe's top five leagues.

These are the stars and solid supporting cast members whose contract situations are worth monitoring in England, France, Germany, Italy and Spain.

Dortmund had been due to hold a public training session to showcase their squad, bolstered by the signings of Donyell Malen and Gregor Kobel, though they had to postpone due to positive tests among the first-team group.

The club initially announced Meunier's COVID-19 results with a statement, before releasing details of Brandt's test on Twitter as they communicated the cancellation of the open training session.

The statement concerning Meunier on the official website said: "Borussia Dortmund defender Thomas Meunier has tested positive for coronavirus. The Belgium international took two tests prior to the training camp in Switzerland and an additional test before departing from Bad Ragaz. All of those tests came back negative. 

"Having had several days off, the player has now tested positive before commencing training this week. Thomas Meunier has since been in isolation. We hope that Thomas' symptoms are as mild as possible and that he gets well soon."

Later on Tuesday, Dortmund's official Twitter account posted the news that Brandt, too, had tested positive.

Marco Rose's new side finished third in Bundesliga last term, with a late push securing Champions League football for the 2021-22 campaign.

The German side failed to keep hold of Jadon Sancho, who moved to Manchester United in the transfer window, though they do still have Erling Haaland to call upon for the new season.

Dortmund get their Bundesliga campaign underway against Eintracht Frankfurt on August 14 before facing Bayern Munich in the DFL-Supercup three days later.
