Arsenal are keeping tabs on Bayer Leverkusen midfielder Hakan Calhanoglu, according to the Daily Mail.
Manchester City and Barcelona are also admirers of the 21-year-old Turkish international, who joined Leverkusen from Hamburg in the summer. The Gunners were aware of the situation in the summer as they had watched Calhanoglu last season, but opted against making a bid.
He has scored five times for the German side this season, including the only goal in the first-leg of their Champions League last-16 tie against Atletico Madrid.
Despite being a full Turkish international, Calhanoglu was born in Mannheim, Germany. He began his career at Karlsruher before joining Hamburg in 2012. His move last summer to the Bundesliga rivals cost 14 million euros.
Meanwhile, Serie A flop Lukas Podolski has admitted he could return to Arsenal in the summer. The striker has yet to score for Inter Milan where he has been on loan since January. Manager Roberto Mancini is growly increasingly frustrated with the German and it is unlikely his loan deal will be turned into a permanent one.
The 29-year-old told Sport Bild: "The Arsenal chapter has by no means been closed.
"I still have a year left on my contract and always got along really well with the guys and the fans.
"But because I was not allowed to play a lot in my last half year, I needed to try something else. When I retire at one point, I can say that I have played in three top leagues: Bundesliga, the Premier League and Serie A."
Most Arsenal fans were glad to see the back of the man signed from Cologne in 2012. He has scored 19 times in 60 appearances for the north London side but saw his appearances in the side become limited due to the progression of Olivier Giroud.
The signing of Alexis Sanchez in the summer meant he had to settle for a place on the bench, until Milan offered him a short-term escape route. There is no buy-out option in Podolski's loan move, something the Italian fans will probably be relieved about.
