The World Cup group stage is over, and many players have caught the eye with their impressive displays ahead of the transfer window.
Group G saw Germany predictably run away with the group, claiming top spot with two wins and a draw, but the United States coming in second place ahead of Ghana and Portugal was something of a surprise. Ghana were embroiled in a row over bonus money which saw Kevin-Prince Boateng and Sulley Muntari sent home, whilst Portugal struggled throughout as Cristiano Ronaldo couldn't carry them through.
There were some great performances in Group G, most notably from Germany forward Thomas Muller, who hit four goals in the group stage, as well as the previously ineffectual Premier League midfielder Jermaine Jones and former Fulham hero Clint Dempsey as the drove USA in to the last 16 – but Arsenal should be looking to sign one of Germany's key players.
With a three-man midfield used by Joachim Loew to support Mario Gotze, Mesut Ozil and Muller in attack, there was plenty of emphasis on getting his midfielders to keep possession before waiting for the right moment. His midfield selection surprisingly didn't include Bastian Schweinsteiger in the first two games of the group, as he chose to go with Toni Kroos, Philipp Lahm and Sami Khedira – and it's the latter that will have proved the most to Gunners boss Arsene Wenger.
The Real Madrid man recovered from a long-term knee injury just in time to feature at the World Cup, but there were plenty of question marks over just how good he would be upon his return to the side. Yet the 27-year-old has put those fears to bed with a number of impressive displays in Brazil – so why could Arsenal sign him?
Real Madrid seem intent on signing a new central midfielder this summer, and have subsequently been strongly linked with moves to sign Chelsea's Ramires, Juventus' Arturo Vidal and even Khedira's international team mate Kroos. It seems that if they can land one of them, Khedira could be allowed to leave the club – and Arsenal must keep tabs on the situation.
A friend of Gunners playmaker Ozil, Khedira could certainly be persuaded to sign for Arsenal, with a £23m bid reportedly lined up. Having witnessed Mikel Arteta struggle in the heart of midfield last season, adding a more physical presence like Khedira would be the ideal move for Arsenal – and it seems that they would be able to secure his signature if Madrid land a midfielder.
