Celtic put on red alert as old boss Martin O’Neill eyes managerial return aged 68 with Neil Lennon under pressure

MARTIN O’NEILL’S wish for a managerial comeback will put Celtic on red alert.

The experienced 68-year-old has not worked since a brief spell at Nottingham Forest — but is looking for a return soon.

O’Neill has sounded out a couple of agents about finding him a club as he itches for a new challenge.

The Irishman would ideally like to work in England but Celtic will be in the market for a boss in the new year if results do not improve.

O’Neill is a legend there after his first spell, though he would need a new coaching team this time.

The Glasgow giants have also considered Steve Clarke — but Scotland making the Euros means it will be difficult for him to move before then.

Hoops’ feelers have gone out about Paul Lambert, however, he is in contract at Ipswich.
