McKenna has the attributes to be a very good centre half. First and foremost he is a good defender, is quick and is naturally left sided (something no Celtic CH is). On the ball he is better than he is given the chance to show at Aberdeen, his Scotland performances have shown that. Brendan Rodgers has said in the past that he wants to have a core of Scottish players in his team, and to date he has done that.
McKenna is the best Scottish CH available, the manager obviously likes him, sees the potential to develop him further and if he is affordable then we should back the manager and sign him. And he’s left sided.
