Arsenal have made a £6million bid for highly-rated Schalke right-back Atsuto Uchida, according to the Daily Star.
The 25-year-old defender has been heavily linked with a move away from the Bundesliga club this summer, and north London has been touted as a possible destination.
Gunnners boss Arsene Wenger is keen to strengthen his defensive ranks before the close of the transfer window, and with less than two weeks until the deadline has made a formal bid to sign Uchida.
The Japanese international arrived in Germany from boyhood club Kashima Antlers in 2010, and has established himself as an important part of the Schalke first-team squad.
With 60 international caps already to his name, Uchida has a vast amount of experience, and would provide a useful option for Arsenal in 2013/14.
Despite having opened negotiations with Bacary Sagna over a new contract, Wenger might still look to add another full-back to provide competition for the Frenchman and Carl Jenkinson.
After an embarrassing 3-1 opening day loss at home to Aston Villa in the Premier League on Saturday, Arsenal fans are putting pressure on Wenger to start spending some money.
The free transfer capture of Yaya Sanogo represents the only business conducted so far during the summer transfer window.
Failure to add any other recruits could result in Arsenal falling even further behind the likes of Manchester United, Manchester City, Chelsea, and even north London rivals Tottenham in the race for Champions League qualification this season.
