Olympiacos centre-back Pape Abou Cisse is attracting major Premier League interest.
The Daily Mail says Liverpool, Arsenal and Everton sent scouts to Istanbul for Olympiacos' Europa League clash with Fenerbahce – seeing Cisse keep a clean-sheet as the visitors won 3-0 to seize control of Group D.
The Greek champions' defence has been rock solid this season, with the 26-year-old starting alongside former Gunners centre-half Sokratis Papastathopoulos and conceding only twice in five league games.
Cisse has been the subject of several inquiries, with Liverpool showing the most intent so far.
The centre-back has earned a spot on the Reds' transfer shortlist, as the Merseysiders look to strengthen at centre-back.
