After Koulibaly signs, Napoli line up Agger

Napoli have completed the signature of Kalidou Koulibaly and reports in Italy suggest their summer spending will continue with a move for Daniel Agger.

Rafa Benitez has called for reinforcements in the summer and they are already starting to arrive with the completion of a deal for Racing Genk's Kalidou Koulibaly.

While towering Frenchman Koulibaly can play either as a defensive midfielder or a centre-back, Napoli still seem keen to try and strengthen that area of the pitch.

It has been a positive campaign for ex-Liverpool boss Benitez whose side finished third in Serie A and won the Coppa Italia, but they went out of the Champions League at the group stage despite a gutsy effort.

The problem all too often this season was vulnerability in defence and the lack of an enforcer to protect the back line.

Napoli have been linked to a number of defensive targets and are expected to add more names than just Koulibaly.

An attempt to sign Javier Mascherano from Barcelona has reportedly failed and Italian newspaper Il Mattino believes Napoli will now look to Liverpool defender Daniel Agger, a player they have been frequently linked with over the last few months.

Agger's future at Anfield is uncertain. While the Danish defender has admitted being frustrated at having to sit out many of Liverpool's big games this season and says he won't be third choice, he claims he isn't thinking about leaving and will let the club make that decision.

Il Mattino insists that a meeting between Benitez and Napoli owner Aurelio De Laurentiis ended in the Spanish tactician calling for the funds to swoop for Agger but that Arsenal captain Thomas Vermaelen is still also on the radar.

Napoli would offer Agger the chance to be a pivotal part of a title-chasing side who will be in the Champions League, but it all depends on where Brendan Rodgers sees him fitting in the pecking order next season.
