Celtic need strong manager like Neil Lennon - John Hartson
Former Celtic striker John Hartson tells BBC Scotland that the club need a stronger manager following the news that Ronny Deila will leave this summer.
And the former Wales international says Neil Lennon, who was Celtic boss for four years until 2014 and who says he would welcome a return, could be the kind of man to fit the bill.
However, Hartson thinks Hibernian manager Alan Stubbs, former Manchester United boss David Moyes and Brendan Rodgers, previously of Liverpool, are also likely to be interested in the vacancy.
