Arsenal are targeting a summer swoop for Roma defender Kostas Manolas, Football Insider sources understand.

The Gunners are eyeing the £30million-rated centre-back two years after a deal to sign him from Olympiakos collapsed at the eleventh hour.

An Arsenal recruitment source has told Football Insider that Manolas is once again on the radar of the north Londoners as they plan to bolster their central defence in the summer.

Arsene Wenger has highlighted the position as one of his priorities in the forthcoming window.

The Gunners have only three senior central defenders, including Per Mertesacker, who turns 32 in September and is out of contract in June 2017.

Manolas has emerged as one the best young defenders in Europe since joining Roma in a £10.3million deal in the summer of 2014.

The 24-year-old has been a mainstay of the Serie A side this season and, with three years still remaining on his contract, his value has increased considerably.

The source told Football Insider that Arsenal offered £8million for Manolas two years ago and held extensive talks with his camp but they were trumped by Roma after Bayern Munich had bought Moroccan star Mehdi Benatia from the Italians for £30million.

Chelsea have also been strongly linked with a summer move for Manolas as they look to replace John Terry.

In other Arsenal transfer news, the club have made an offer for a 35-goal striker.
