Aidan Magee, Sam Lyon and Peter Staunton discuss the major talking points from the summer market
But the window is not done yet, not by a long shot. Manchester United continue to go in search of big-name reinforcements in defence and midfield as Louis van Gaal prepares for his first season in English football.
The reigning Premier League champions, Manchester City, have also been in busy, shrewdly adding depth to an already impressive squad.
But will it be enough to retain the title? With Chelsea bringing in Thibaut Courtois, Cesc Fabregas and Diego Costa, among others, Jose Mourinho's hand is a strong one.
Arsene Wenger, buoyed by success in the FA Cup, might have something to say about it too given the £32m purchase of Alexis Sanchez, while Liverpool are ploughing money into their squad following the departure of Luis Suarez.

So watch the video above to find out all the latest transfer news and the ramifications for Europe's major players.
