Premier League
The dominant story of the summer window is Manchester United's sweeping squad overhaul. The club have moved on a remarkable number of players: veteran midfielder Casemiro departed on a free transfer to MLS side Inter Miami in late July, while defenders Radek Vítek and Tyler Fredricson both left on transfers to Middlesbrough and Swiss side Lausanne respectively. Goalkeeper Altay Bayındır has gone out on loan to Celta Vigo, Sonny Aljofree left on a free to Rotherham, and academy product Ethan Williams dropped down to Peterborough. The sheer volume of outgoings paints a clear picture: United are stripping back their bloated squad with intent.
Tottenham, meanwhile, feature only as the club who lost Thompson, and there is no further confirmed incoming business from Spurs.
Ligue 1
Marseille have had an extraordinary window, and not necessarily in a way their supporters will celebrate. The French club have lost six players in confirmed moves. Most significant is goalkeeper Gerónimo Rulli, who completed a transfer to Manchester City in mid-August — the window's headline deal and arguably the most consequential move in this entire roundup, representing a clear upgrade in depth for the club. Defender Facundo Medina followed him out of the door, joining Bundesliga side Bayer Leverkusen on a transfer. Forward Pierre-Emerick Aubameyang departed on a transfer to Deportivo La Coruña, winger Traoré went to Genoa on loan, and Bilal Nadir left as a free agent to join Hamburger SV. Marseille appear to be in a phase of significant structural change — whether that represents a planned rebuild or financial necessity, the sheer scale of the exodus will raise questions heading into the new Ligue 1 campaign.
Bundesliga
Bayer Leverkusen are the Bundesliga's most active club in this window, bringing in Facundo Medina from Marseille on a transfer. Hamburger SV also feature, adding Bilal Nadir on a free from Marseille.
La Liga
Celta Vigo have bolstered their goalkeeping options by taking Altay Bayındır on loan from Manchester United, a practical short-term solution as the Spanish side prepare for their league campaign. Deportivo La Coruña have signed Pierre-Emerick Aubameyang on a permanent transfer from Marseille.
Serie A
It is modest business on paper, but loan deals of this kind can prove shrewd if the player hits form quickly in a new environment.
