Martin O’Neill: Celtic job might only last until Thursday if I lose to Falkirk

O'Neill said he stands by opinion that Hearts winning the Premiership would reinvigorate Scottish football, that Celtic lack physicality, and that Rangers are not title contenders.

Martin O’Neill vowed to enjoy his shock return to Celtic Park after agreeing to a comeback following a request by the man who gave him the manager’s job a quarter of a century ago.

But the 73-year-old admitted he might be back out of a job on Thursday if Celtic cannot beat Falkirk in his first game back.
