Liverpool have joined Manchester United in the race to sign Benfica star Nicolas Gaitan and have made the Argentinian winger one of their primary transfer targets for this summer.

Liverpool have watched Gaitan in action on several occasions this year during some domestic and European fixtures, talkSPORT report.

Reds boss Brendan Rodgers has been looking to strengthen his wing position in particular during recent months, with Mohamed Salah and Yevhen Konoplyanka both targeted, but the Anfield club were unable to secure either players signature.

Salah ended up moving to rivals Chelsea, but Liverpool could yet swoop again for the Ukrainian who played against Tottenham in the Europa League last Thursday.

Although, it now looks as though Liverpool have joined United in the hunt for Gaitan. United have been linked with the player for the past two summer transfer windows and reportedly came closest to signing him in 2012.

Liverpool are looking to strengthen their squad ahead of a return to Champions League football next season, which is looking increasingly likely.

Gaitan would command a fee of around £16 million to take him away from Benfica, whom he joined from Boca Juniors in 2010. Gaitan has made 26 appearances for the Portuguese league leaders this year, scoring four goals.
