Atletico Madrid right-back Juanfran has turned down an offer from Arsenal to replace Bacary Sagna at the Emirates Stadium again - having already rejected the Gunners last summer.

The 29-year-old defender played a crucial role in Atletico Madrid's La Liga title success as well as their remarkable run to the Champions League final and is currently with the Spanish national team after being named in Vicente Del Bosque's 30-man preliminary squad.

Arsenal made a bid to secure his services last summer, offering four times more than he was earning in La Liga. However, the Spanish international refused to leave Diego Simeone's side and instead committed his future to the Vicente Calderon by signing a new contract until 2017.

But with Wenger desperately looking for a replacement for his long serving right back Sagna, AS report that Arsenal renewed their bid for Juanfran a couple of weeks ago – only for the Spaniard to snub the Gunners once again.

Meanwhile, reports in France continue to suggest Sagna will join Manchester City this summer after failing to agree a new deal despite being locked in talks with the Gunners for most of the season.

Should Sagna's move to the Etihad be confirmed and with Juanfran unlikely to move to the Emirates, Wenger will be left to look elsewhere for someone to fill the void expected to be left by the French international.

And according to the reports, Arsenal are keeping a close eye on Toulouse youngster Serge Aurier, Southampton right-back Calum Chambers and Schalke's Atsuto Uchida.

Aurier himself recently fuelled speculation of his potential move to Arsenal, claiming that it will be hard to turn down an offer from Wenger's side.

"It is certain that I would be a little disappointed to stay in Toulouse, especially after a season like this," Aurier said.

"I would not refuse Arsenal. This is a club that has a history, which has hosted many French-speakers who also have a French coach. Plus Arsenal is always looking for titles and playing in the Champions League."
