The transfer window is now well and truly in full swing, with Premier League clubs parting with over £360million after only 26 days, according to a recent reports.In fact, Deloitte’s Sports Business Group believe this transfer window may surpass the £630m record set last year, as the top flight’s big guns continue to strengthen their squads.There have been a number of highlights so far, including Chelsea’s triple Spanish capture of Diego Costa [£32m], Cesc Fabregas [£30m] and Filipe Luis [£16m], but it’s the deals for the game’s up-and-coming young stars that demand more attention.Luke Shaw became the world’s most expensive teenager this summer following his £27m move to Man United, joining 24-year-old Ander Herrera at Old Trafford, while Liverpool splashed out close to £30m on 20-year-old winger Lazar Markovic and 20-year-old midfielder Emre Can.But there is still a host of untapped talent around Europe that are yet ply their trade on English shores, so talkSPORT takes a look at the continent’s brightest stars…Click on the arrow above to check out the best young players in Europe! IIkay Gundogan – 23 – The German midfielder was the subject of a pile of interest from across Europe following a run of spectacular displays for Borussia Dortmund, though talks of a possible move has subsided since he was sidelined with a major injury last season. A rumoured switch to Barcelona never came to fruition, and while Man United and Arsenal were interested in bringing Gundogan to the Premier League, he instead signed a new contract at Dortmund having suffered nerve damage in his back last August. He hasnt played a competitive minute of football since, but that shouldnt rule out a possible future move to the English top flight, and the Gunners could lead the race for the talented playmaker with their contingent of Germany internationals. Zakaria Bakkali – 18 – Currently one of the most in demand teens on the planet. The lightweight but terrifyingly quick winger has earned plenty of suitors following his recent step up into the PSV first team, having signed as a youth player in 2008 from Belgian outfit Standard Liege. Liverpool are continuously linked with attacking options following the exit of Luis Suarez, and the wonder-kid is reportedly keen on a move to Anfield. Recent rumours suggest the Reds have made an offer for the young Belgian, but they need to move quickly to wrap up a deal, with Arsenal and Tottenham also keeping tabs. Raphael Varane – 21 – Real Madrid signed the young defender from Lens on 2011 on the recommendation of club legend Zinedine Zidane, arriving at the Bernabeu for a whopping £10million as a 17-year-old. Described by Zizou as “the finest French centre-back since Laurent Blanc”, Varane was superb for the European champions since forcing his way into the first team, yet Chelsea boss Jose Mourinho, the man who brought the youngster to Spain, reportedly remains confident the Blues can snap up the youngster this summer. Julian Draxler – 20 – Hailed as one of Europes brightest young stars, the German was linked with a move to English shores throughout last season, but while Arsenal were reportedly close to signing the midfielder, he eventually stayed at Schalke – but for how much longer? In fine form in the Bundesliga and Champions League, Draxler would command a hefty fee if Schalke finally decide to cash in this summer and he could yet head to north London, with Tottenham said to have submitted a £17million offer. 10 Memphis Depay – 20 – The PSV winger emerged as one of the breakout stars of the summers World Cup in Brazil, with a number of dazzling displays off the bench for Louis van Gaals Oranje side. Frightfully fast down the wing with the technical skill to boot, Depay only really broke into the Dutch sides first team last season but has impressed in such a short amount of time. He is strongly linked with a return to Van Gaal at Man United this summer, though PSV has indicated the Red Devils would have to fork out more than 21million for the starlet. Stephan El Shaarawy – 21 – Nicknamed the ‘Little Pharaoh’, Manchester City, Arsenal, Chelsea and Liverpool have all tracked and been linked with moves for the tricky Italian over the past few seasons. A clever playmaker but still very much a raw talent, there are countless YouTube montages showcasing El Shaarawys skills. He apparently loves life at AC Milan, though his agent has previously admitted the youngster may have to leave in search of regular first team football having found himself down the pecking order after an injury-hampered campaign last season. 10 10 Isco – 22 – The Spain starlet only arrived at Real Madrid last summer, but it already seems the talented playmaker is on his way out from the Bernabeu following the recent big-money arrival of James Rodriguez. Madrid are keen to offload the £23million man to make room for the Colombian attacker, with Liverpool reportedly keen to add to their attacking options with yet another big summer signing. While the Spanish press say Isco is happy to stay and fight for his Los Blancos place, the club may look to cash in while interest is high. Viktor Fischer – 20 – The Danish wonder-kid is highly-rated and well loved at Dutch champions Ajax, though a number of other European sides are interested in prying him away from Amsterdam this summer. Fischer signed for Ajax as a 16-year-old in 2011 and has emerged into a great attacking asset ever since breaking into the first team. Manchester United, Chelsea and Italian outfit Roma have all tracked the youngster over the past seasons, though the Dutch giants are desperate to keep hold of their latest prospect to maintain his rapid rise. 10 10 10 10 10 Paul Pogba – 21 – What more can be said about the battling Frenchman? Shunned at Manchester United by manager Sir Alex Ferguson, Juventus gave him a chance and boy, how the midfielder has delivered. Often likened to a young Yaya Toure, Pogbas presence in Juves midfield was exactly what United were missing last season, so much so that axed boss David Moyes attempted to re-sign the youngster in January. He was handed the Golden Boy award – given to the best under-21 player in Europe – last year, and there is little feeling his rise will falter any time soon. Again linked with a return to Old Trafford this summer, Chelsea have also shown an interest this time around, and while the Turin side insist Pogba isnt going anywhere, the Premier League giants certainly have to finances to test their resolve. 10 10 Bruma – 19 – A product of Sporting Lisbons famous youth academy, the pacey winger was previously linked with switches to Manchester United and Chelsea, though the Portugal Under-19s star eventually signed a five-year deal with Galatasaray last September. Bruma has found life difficult in Turkey since his arrival, though, as only a few months after his £8.4million move he suffered a serious knee injury and was shipped out to Super Lig side Gaziantepspor for the rest of the season, where he failed to make an appearance. Having previously showcased enough to tempt a host of clubs, though, it may be that his Premier League suitors come calling again.
