- Manchester United have made all of the early running in the transfer market so far this summer, having completed deals for Phil Jones, Ashley Young and David De Gea.
Highly-rated Jones opted to move to Old Trafford from Blackburn rather than to Liverpool or Arsenal, while Young joined from Aston Villa for £17 million.
Spanish goalkeeper De Gea was the latest acquisition by Sir Alex Ferguson, with the 20-year-old signed as a replacement for retired Edwin Van der Sar.
- Chelsea have yet to make any significant moves during the transfer window, but that is now expected to change since the appointment of Andre Villas-Boas as manager.
The 33-year-old will reportedly raid former club Porto for a number of their star turns, with £26.5 million striker Falcao hoping to follow Villas-Boas to Stamford Bridge.
- Liverpool have been left frustrated so far - missing out on Phil Jones, Ashley Young, Connor Wickham and Gael Clichy - but did complete the signing of Jordan Henderson from Sunderland.
The Reds have also ramped up their efforts to sign Stewart Downing from Aston Villa, while a fee for Charlie Adam was agreed on Wednesday.
- Arsenal are on the verge of completing their second signing of the summer, with Lille forward Gervinho undergoing a medical with the club on Wednesday.
The acquisition of a new centre-back is regarded a priority for Arsene Wenger, with Gary Cahill and Chris Samba reportedly in his sights.
- Tottenham have so far only snapped up veteran goalkeeper Brad Friedel on a free transfer, but Harry Redknapp is after a proven goalscorer.
Villarreall's Giuseppe Rossi takes the fancy of the Spurs boss in particular, with the north London club having failed to sign him ion January.
- Manchester City have yet to blaze a customary trail, but have gone about their business relatively quietly - signing Gael Clichy and Stefan Savic for £7 million and £6 million respectively.
However, the Citizens will reportedly make a move for Arsenal midfielder Samir Nasri this week, while Napoli striker Ezequiel Lavezzi remains on their radar.
