Arsenal target Sami Khedira has again fuelled talk of a move away from Real Madrid this summer, admitting he is open to "many teams".

Khedira, 27, is out of contract at the Santiago Bernabeu at the end of the season and with little indication of a new deal being agreed, he could begin talks with potential new clubs in the coming months.

The Germany international was relentlessly linked with a move to the Emirates throughout the 2014 summer transfer window but eventually opted to see out the remainder of his contract in the Spanish capital.

Available on a free transfer at the end of the season, Khedira is likely to have a number of options to choose from, with Schalke seemingly keen to offer the midfielder a route back to Germany.

Speaking after his side's 3-4 Champions League defeat to the Bundesliga side, Khedira all but confirmed he would be leaving Real, telling reporters: "Am I open to Schalke? I am open to many teams."

Khedira was greeted with boos as he was substituted in Real Madrid's woeful performance on 10 March as the reigning champions just about held on to a place in the Champions League quarter-finals.

But the World Cup winner has attempted to reassure supporters his focus remains on helping the club in their pursuit of European and domestic success, despite his uncertain future.

He said: "I have also been booed when I came off the bench. I am fully aware I am not a fan favourite here. I will give it my all for the club until the last minute, and what happens in the summer is still a long way off."

Arsenal manager Arsene Wenger has been urged by former players, including John Hartson and Ray Parlour, to consider a move for Khedira but the Gunners will face competition for his signature.

"Of course, Sami Khedira would look good with Schalke. And we would certainly take him if he were on the market," Schalke's sporting executive Horst Heldt said. "But let's not get carried away. There are many clubs who can imagine working with Sami."
