Arsenal are considering a shock move in signing Liverpool defender Daniel Agger, according to the Mirror.

The Gunners currently have Per Mertesacker, Laurent Koscielny and Thomas Vermaelen as the recognised centre-backs in the squad. The Belgium international has one year left on his contract at the Emirates and refused to sign an extension.

Vermaelen has been strongly linked with a move away from the north London club in recent times. Arsenal's league rivals Manchester United and Spanish giants Barcelona are keen on securing a deal for the Gunners' skipper.

Arsene Wenger has already admitted that Vermaelen could leave his current employers in this summer transfer window. The Arsenal manager also admitted that should the former Ajax man leave the Emirates, he will bring in another central defender.

"It [a transfer] could happen, yes. It's a possibility that he goes. If he goes, we have to replace him because he's an important player in our squad," Wenger told Arsenal's official website.

The Frenchman has now set his sights on Agger to strengthen his side's back four and a direct replacement for Vermaelen in the squad. The Danish international saw his first team appearances being limited during the last season.

Agger was sidelined during the start of the previous campaign, which saw Brendan Rodgers use Marin Skrtel, Kolo Toure and Mamadou Sakho in the heart of Liverpool's defence. After he gained full fitness, the 29-year-old found it difficult to break into the Reds' starting lineup.

The Merseyside club have already signed Dejan Lovren from Southampton. With the arrival of the Croatian international, Agger has dropped further down the pecking order and he could see his playing time being restricted in the next season.

Wenger is planning to give Agger an escape route and bring him to the Emirates to bolster Arsenal's back four for the new campaign.

Last summer, Arsenal were interested in signing Luis Suarez, who left Liverpool to join Barcelona in July. The Reds were adamant in letting their star player join the Gunners. It should be seen if Liverpool will allow Agger join their direct league rivals in the ongoing summer transfer window.
