Arsenal cancelled Pierre-Emerick Aubameyang's contract to pave the way for the striker to join Barcelona, while Ousmane Dembele remains at Camp Nou following an eventful transfer day across Europe.

Aubameyang had five months to run on his Emirates Stadium deal but was told he could join Barca on a free transfer, which is set to be announced by the LaLiga giants on Tuesday.

Despite some confirmed interest from at least one club in England, and the threat of not playing for the rest of the season, Dembele opted to stay put in Catalonia until at least the end of the season.

Those players were discussed heavily throughout deadline day, but arguably the most remarkable transfer happened early on Monday when Christian Eriksen officially joined Brentford.

It marks a return to the Premier League – and indeed a football pitch – for Eriksen, just seven months after suffering a cardiac arrest while playing for Denmark at Euro 2020 and subsequently being fitted with a heart-starting device.

Newcastle live up to big-spending billing

In their first transfer window under their new ownership, Newcastle United spent more than any side on the continent and rounded things off by bringing in some much-needed defensive options in Dan Burn and Matt Targett.

Boyhood Newcastle fan Burn joined from Brighton and Hove Albion in a reported £13million deal, while left-back Targett will spend the rest of the season at St James' Park on loan from Aston Villa.

But it was not all good news for the Magpies as they missed out on a deal for France Under-20s striker Hugo Ekitike, who is reported to have had second thoughts and decided to remain at Reims. There was also no move for Jesse Lingard.

Tottenham and Juventus the busiest clubs

Antonio Conte was backed by the Tottenham board on deadline day with the arrivals of Rodrigo Bentancur and Dejan Kulusevski as part of a double deal with Juventus.

Bentancur is reported to have cost Spurs an initial £15.9m (€19m) on a deal that will run through until the end of the 2025-26 season, and he will be joined in north London by Kulusevski on an initial 18-month loan with the option to buy.

It was not all about incoming activity for Tottenham in the final stages of the window, though, as club-record signing Tanguy Ndombele was returned to Lyon for the rest of the season and Bryan Gil and Giovanni Lo Celso were loaned out to LaLiga sides Valencia and Villarreal respectively.

And in a deal that went through more than an hour after the 23:00 GMT cut-off point, Dele Alli joined Everton in a transfer that could potentially earn Spurs £40m should various clauses be triggered.

Having offloaded Bentancur and Kulusevski, meanwhile, Juve further trimmed their squad by allowing Aaron Ramsey to sign for Rangers until the end of the campaign, with those deals offset by the arrival of Denis Zakaria from Borussia Monchengladbach.

Big boys quiet

Manchester City got a deal over the line for Argentina international Julian Alvarez before loaning the young forward straight back to River Plate, but it was otherwise a relatively quiet day for Europe's elite clubs.

Manchester United's only piece of business on Monday was allowing midfield outcast Donny van de Beek join Everton on loan, while Liverpool let Nat Phillips head to Bournemouth for the rest of 2021-22. The second-tier Cherries also signed Todd Cantwell, recently a target for Liverpool, to bolster their promotion ambitions.

Liverpool had hoped to bring in highly rated youngster Fabio Carvalho from Fulham, but a deal is reported to have fallen through shortly before the cut-off point after terms had already been agreed.

There was no such activity for fellow Premier League heavyweights Chelsea, as was the case for the likes of Paris Saint-Germain – despite links with Dembele – Bayern Munich, Inter, Milan and Real Madrid.

But reigning Spanish champions Atletico Madrid did manage to strengthen at left-back by bringing in Reinildo Mandava from French champions Lille.

Other notable deals...

Unsurprisingly, Premier League clubs flexed their financial muscles in a final attempt to strengthen before the deadline.

Crystal Palace turned striker Jean-Philippe Mateta's loan from Mainz into a permanent deal and Burnley signed Wout Weghorst from Wolfsburg, who moved quickly to bring in FC Copenhagen striker Jonas Wind as a replacement.

Elsewhere, Deniz Undav put pen to paper with Brighton before being loaned back to Belgian side Royale Union Saint-Gilloise. The Seagulls also signed Benicio Baker-Boaitey on loan from Porto with a view to a permanent move.
