Juventus boss Claudio Ranieri has revealed he is a fan of Liverpool midfielder Mohamed Sissoko.Sissoko is a reported target for Juve in the January transfer window and former Chelsea manager Ranieri has done little to quell the speculation. 'Sissoko is a player that I like a lot and I know him well,' said Ranieri. 'I have had the pleasure of coaching him at Valencia.' Sissoko, 22, joined Liverpool in the summer of 2005 from Valencia and is under contract with the Merseyside club until June 2011. The Mali international has made nine Barclays Premier League appearances for Liverpool this season but has struggled to hold down a place in Rafael Benitez's first-choice XI.
