Celtic are eyeing released West Brom midfielder Robert Koren.

German club Hanover and Celtic both want to sign Koren after Premiership new boys West Bromwich Albion decided against taking up their one-year option on the midfielder, says the Daily Mail.

The 28-year-old Slovenian skipper, who will lead his country against England in the group stage of the forthcoming World Cup finals in South Africa, was the Baggies' longest-serving player.
