Sky Sports reports that the Hoops will look to sign a left-sided winger once they get a deal for a right winger over the line. The FC Utrecht attacker is said to be high on Celtic’s shortlist as Martin O’Neill looks to improve his options out wide before the window closes. Blake is one of the players Celtic are looking at as they continue to shape the squad for the season ahead. He is already known to Celtic supporters after facing the Hoops at Celtic Park earlier this year. There is no sign yet that Celtic have made a formal offer for the winger.
