Celtic are not currently looking to sign another centre-back, with Martin O’Neill happy with the options already available to him. That comes as Courier Sport reports that Dundee have enquired about taking Dane Murray to Dens Park. Murray was named among the substitutes for Monday’s 1-0 win over Dundee and remains part of O’Neill’s first-team squad. Celtic are not actively searching for another central defender during the current window. Celtic’s decision to reject Dundee’s enquiry also indicates Murray remains close enough to O’Neill’s plans to be called upon when required.
