As Europe's elite enjoy a well-earned summer break, attention has quickly turned to an exciting period of transfer action.

Countless stars will be on the move in the coming weeks, with talents such as Jude Bellingham and Lionel Messi having already announced their next destinations.

Those transfers do not become official until the summer window officially opens, however. 

We have covered all the key information and dates surrounding the window below.

When does the summer 2023 transfer window open?

The summer transfer window officially opens for business on Wednesday, June 14 for Premier League and Football League clubs.

However, that only relates to domestic deals, with any agreements involving players based overseas unable to be officially ratified until Saturday, July 1.

Those dates are unlikely to prevent clubs announcing moves in advance, though, as displayed by Liverpool confirming their impending capture of Alexis Mac Allister from Brighton.

French clubs can start confirming deals from June 10, leagues in Germany and Italy open their windows on July 1, while LaLiga clubs can start trading on July 3.

When does the summer 2023 transfer window close?

All of Europe's top leagues will see their window slam shut on on Friday, September 1.

Bundesliga clubs must get their work done by 5pm, while Serie A will shut up shop at 7pm. Ligue 1 business finishes at 10pm and the windows close in the Premier League and LaLiga at 11pm BST.

Big deals to look out for

As mentioned, some of the summer's biggest sagas have already been resolved.

English starlet Bellingham, 19, is leaving Borussia Dortmund for Real Madrid for an initial £88.5million fee, while Messi, 35, will join MLS outfit Inter Miami upon the expiration of his Paris Saint-Germain contract.

More dramatic deals are guaranteed, though.

The future of Tottenham talisman Harry Kane has rarely looked more uncertain, with Spurs' failure to qualify for Europe putting the likes of Manchester United, Real Madrid and Bayern Munich on red alert.

After running Manchester City close in the Premier League title race, Arsenal will be desperate to strengthen their ranks further and a move for a midfielder appears Mikel Arteta's top priority.

West Ham skipper Declan Rice and Brighton's Moises Caicedo — who nearly joined the Gunners last January — are thought to top their wish list.

Elsewhere, Saudi Arabia's big-spending Pro League clubs are certain to continue their lavish attempts to lure some of world football's prized assets to the Middle East.

With Karim Benzema and Cristiano Ronaldo already secured, more household names look certain to follow.
