With Euro 2012 over we are gradually seeing an increased number of signings by English Premier League Clubs. However, what are the best bits of business that have been done so far this summer?

Chelsea seems like a good place to start as they snapped up the much sought after Eden Hazard from Lille for a cool £32 million. The young Belgian winger comes with a high reputation and was wanted by a whole host of clubs worldwide, including Manchester United and Manchester City. He could potentially be the best signing of the summer so far (on paper anyway). Chelsea will be hoping that by capturing the 21 year old and 23 year old Marko Marin from Werder Bremen that they can build on their Champions League victory and start building a younger squad.

Spurs have also signed a couple of quality player in Gylfi Sigurdsson (£8 million) and Jan Vertonghen (£10 million) as well as a new manager in Andre Villas-Boas. Although the contract extension signed by Gareth Bale arguably is the best bit of business done by Tottenham so far this summer. Villas-Boas will be keen to hold on to his main players and although Rafael Van der Vaart looks set to remain at White Hart Lane, the same cannot be said for Croatian midfielder Luka Modric. AVB has already voiced publicly his desire to sign Portugeuse midfielder Joao Moutinho from his former club Porto to replace Modric. However, whether Porto wants to sell the player is a completely different matter.

London rivals Arsenal have been slightly quieter, but have completed deals for Olivier Giroud from Montpellier (£12 million) and experienced German striker Lukas Podolski. With Robin Van Persie recently refusing to commit his future to the club, a striker of the calibre and track record of Podolski could be very timely for The Gunners. That twinned with the raw talent of Giroud could potentially pose problems for many teams in the Premier League.

Manchester United have also been quiet by their standards in the transfer market. Apart from signing Nick Powell from Crewe (£6 million), they completed a move for Shinji Kagawa (£12 million) from Bundesliga champions Borussia Dortmund. Sir Alex and his men will be hoping Kagawa can carry on his form from last season, which saw him score 17 goals in 43 appearances. Surprisingly, there has been no transfer activity from the noisy and rich neighbours Manchester City, with not a single signing taken place in the window.

New Liverpool boss Brendan Rodgers unveiled his first signing, with striker Fabio Borini signing from Roma for £10.5 million. The pair worked together at Swansea during the 2010/2011 season with Borini scoring 6 goals in 9 appearances. The striker appears to have been signed to coincide with Rodgers style of play. This has also lead to rumours of Andy Carroll ending his time on Merseyside, with West Ham and former club Newcastle reportedly interested. Newcastle have already had one bid for a season long loan turned down. Similarly, Merseyside rivals Everton have signed one player but on a free transfer. That player is Steven Naismith who arrives from Glasgow Rangers. This has the potential to be a great signing for Everton as Naismith is a well rounded player and one which would work very well within David Moyes team, even more so as he has the chance to re-ignite his successful partnership with former team-mate and formidable forward Nikica Jelavic.

QPR have made numerous signings so far in the transfer window including defenders Ryan Nelson from Tottenham on a free transfer from Spurs and also Brazilian Fabio on loan from Manchester United. Mark Hughes has also secured the services of England goalkeeper Robert Green from West Ham as well as striker Andy Johnson from Fulham both on a free. However Rangers have also splashed some cash and brought in some quality, with Malian midfielder Samba Diakite (£3.5 million) joining the club from French club Nancy. They have also brought in the experienced Ji-Sung Park from Manchester United for £2 million. By the looks of things Mark Hughes and Tony Fernandes have brought in players that could and that they hope can steer them clear of the relegation dog fight.

So what have the new boys been up to? Well Reading secured the signature of Pavel Pogrebnyak from under the noses of Fulham. The Russian striker was in great form for Fulham during his loan spell in the second half of the season, scoring 6 goals in his 12 appearances for The Cottagers. If he can maintain that sort of form this season, it could go a long way to helping Reading survive in their return to the top division. West Ham and Sam Allardyce have also been busy; signing four players so far. Experienced goalkeeper Jussi Jaaskelainen arrived on a free from Bolton to team up with his old manager. The Hammers have also signed defender George McCartney from Sunderland, midfielder Mohammed Diame from Wigan and goalkeeper Stephen Henderson from Portsmouth all on free transfers. Southampton signed striker Jay Rodriguez from Burnley for £7 million and have also been one of the many clubs benefitting for the downfall of Glasgow Rangers, signing Steven Davis on a free transfer.
