Manchester United manager Louis van Gaal has refused to rule out the possibility of signing goalkeeper Victor Valdes.
Manchester City boss Manuel Pellegrini says he is confident that England goalkeeper Joe Hart will sign a new contract.
Our Nick Hext has taken stock of the season so far and picked his top team from the players who found a new Premier League club in the summer.
There is work for plenty of the top-flight clubs to do in the January transfer window but who spent wisely before the end of August?
This side is selected from the players who are providing value for money and making the biggest impact on English football.
It didn't take long for West Brom to decide to sign Foster on a permanent basis after his successful loan spell at The Hawthorns last season. He was named Albion's supporters' Player of the Year and players' Player of the Year and impressed again this term prior to injury problems in November. The former Manchester United man is now back to further enhance his reputation and will surely remain between the posts for the Baggies for many years.
Southampton had to play the waiting game before agreeing a fee for Clyne in the summer but it was well worth the patience. The full-back has made the step up from the Championship with ease by becoming one of the main bright sparks in the Saints' season to date. The right-back is pleased he turned down the chance to join Newcastle prior to his move to St Mary's and Nigel Adkins is certainly pleased with how the 21-year-old is performing.
Villa have been way out of form in their last three games but there has been plenty to like about some of their summer recruits (Ashley Westwood also makes this team and Matthew Lowton, Joe Bennett and Christian Benteke all went close). Vlaar quickly took over the captaincy at Villa Park and we have all clearly seen just how much his influence was missed in the heavy defeats against Chelsea, Tottenham and Wigan. The Dutchman has plenty of experience from his time with Feyenoord and you can be sure Villa will be a stronger proposition upon his return.
City were busy on deadline day with Richard Wright, Maicon, Scott Sinclair, Javi Garcia and Nastasic all arriving at the club. The other four (although don't write off Garcia just yet) haven't made too big an impact but the 19-year-old Serbian has proved to be a quality addition. There is much more to come from him and David Platt says that it is an "old head on young shoulders" responsible for the quick acclimatisation to life in England. Already becoming a first-choice member of the City starting XI is a big achievement and the Etihad Stadium fans can be very pleased with this signing.
Rose has proved to be a superb loan addition for Sunderland. The full-back has yet to prove his worth on a consistent basis for Tottenham and the temporary switch to the North East is working out well for all parties. Martin O'Neill admits the 22-year-old is now playing with more "freedom" at the Stadium of Light and there is more to come for the rest of the campaign.
I didn't expect Moses to provide too much for Chelsea (see Sinclair's impact at Manchester City) but that opinion has been proved wrong. Wigan fans have been raving about the versatile forward for a long time and they have been proved right as to his capabilities on a bigger stage. The 21-year-old has four goals to his name so far for the Blues and it's his direct running that has proved the biggest asset to his new club. Rafa Benitez has lots of quality to work with but you can be sure the former Crystal Palace youngster will be getting more chances to shine.
Villa aren't making too many positives headlines at the moment but fans of the club should still feel good about this signing. The 22-year-old has made the step up from League Two football at Crewe last season to the bright lights of the Premier League and proved that is quality to be had further down football's pyramid. Paul Lambert is right to point out the midfielder's best skill is 'never giving the ball away' and that is certainly something every club in the world could do with.
Dembele has already established himself as a player Tottenham can't do without. The White Hart Lane side have been infinitely better with the Belgian starting and it's not a surprise to see plenty of praise heading the way of the former Fulham man. You can fully understand why Martin Jol didn't want to lose his star man just before the deadline but that loss is Spurs' gain. Andre Villas-Boas' side have a great chance of a top-four spot this season and his summer signing is the main man to get them there.
The playmaker has certainly added more magic to the Premier League since his arrival from Malaga. Arsenal have been the beneficiaries of his talents and Arsene Wenger can be happy this is one signing that can't be used to beat his reputation with. Cazorla's hat-trick against Reading on December 17 created lots of headlines and there has been a real consistency to his game so far at the Emirates. The Gunners certainly need more of the same from the Spaniard for the rest of the season.
A very, very simple choice. Van Persie is clearly the reason United are ahead of rivals City in the title race and also gives the Red Devils more to worry Real Madrid with in the last 16 of the Champions League. There have been 17 club goals already from the Dutchman so far this season and it would be surprising in the extreme if more don't follow for the remainder of the campaign. Arsenal have missed him but the Old Trafford fans don't care with RVP now one of their own.
You won't find any better £2million deals these days. Michu had already made his mark at Rayo Vallecano but his career has been taken to new levels with his performances for Swansea. Michael Laudrup knew just what he was getting when the forward made the move to Wales but even the Swans chief must be surprised at just how much class the Spaniard has provided. The Michu magic has certainly captivated the Liberty Stadium crowd with 14 goals to his name so far this season.Subs: Hugo Lloris (Lyon to Tottenham, £7.9million), Matthew Lowton (Sheffield United to Aston Villa, undisclosed), Jan Vertonghen (Ajax to Tottenham, undisclosed), Claudio Yacob (Racing Club de Avellaneda to West Brom, free), Oscar (Internacional to Chelsea, undisclosed), Steven Fletcher (Wolves to Sunderland, undisclosed), Christian Benteke (Genk to Aston Villa, £7million)
