Napoli boss Rafa Benitez has made Benfica defender Ezequiel Garay a priority summer signing, according to reports. The race to sign the Argentine centre-back is heating up with Napoli trying to steal ahead of Manchester United and Monaco. Garay has been one of the most impressive performers for the Portuguese giants this season, helping the club to the league title. The 27-year-old former Real Madrid player is tipped to leave the club last summer, with United very much in the hunt. However, according to Spanish source Frichajes.net, former Liverpool boss Benitez will go all out to land the defender this summer and is encouraging his board to reach a swift agreement. That will come as a blow to United who must first appoint a new manager in the wake of David Moyes sacking. The Old Trafford outfit will need to rebuild their defence this summer as departing captain Nemanja Vidic gets ready to join Inter Milan.
