Arsenal are looking to resolve their defensive woes by signing Lukas Klostermann, 20, from RB Leipzig.
The newly-promoted Bundesliga side value the youngster at £25m, a surprisingly high figure given he has made just 13 appearances for their first team since joining from VFL Bochum in 2014.
Currently used by Leipzig as a right back, he is highly-rated as a central defender with many believing that to be his natural position.
Klostermann is in Rio at the moment with the German Olympic football squad and has played in both their matches so far, alongside potential future team-mate Serge Gnabry, 21.
If Arsenal pursue their interest, a quick signing is unlikely, making Klostermann one for the future for Arsene Wenger. The Gunners requirements are more immediate with both Per Mertesacker and Gabriel ruled out of the opening Premier League fixtures.
The north London club have held talks with Valencia over Shkodran Mustafi, 24, and a return to the Premier League seems imminent for the former Everton defender.
His time on Merseyside was inauspicious but his career has taken off since then, with a dozen caps so far for his country.
The Spanish club are reportedly looking for a replacement after which he will be allowed to move to Arsenal for a fee of around £20m.
