John Hartson suggests three ex-Celtic players to potentially replace manager Ronny Deila

John Hartson says it's time for Ronny Deila to leave Celtic.

Former Celtic striker John Hartson has told The Scottish Sun that he thinks it's time for Ronny Deila to go - and wonders whether the Bhoys will look to former players to replace him.

Deila, 40, arrived as Neil Lennon's replacement at Celtic Park back in the summer of 2014, and enjoyed a promising first season in Glasgow, winning the Scottish Premiership title and the Scottish League Cup - though success in Europe evaded the Norwegian.

His second season has been one filled with criticism. After crashing out of both the Champions League and Europa League, Deila has seen his side stumble towards the Premiership title, and were dumped out of the Scottish League Cup by Inverness in January.

The few sections of supporters who were backing Deila have now largely vanished since Sunday's Scottish Cup semi-final defeat to Old Firm rivals Rangers, who sit a division below the Bhoys.

Many now expect Deila to leave the club at the end of the season, and former Celtic striker John Hartson has told The Scottish Sun that it's time for the Norwegian to go - although not immediately.

Hartson believes that Deila should be allowed to see out the season and win the title again before leaving, and the Welshman posed three possible names for the job.

Ex-Celtic players David Moyes, Neil Lennon and Roy Keane are all in Hartson's thinking for the job, and he ultimately won't be sad when Deila does receive his marching orders.

"There’s no point in sacking him right now," said Hartson. "For all that Celtic are dire, they’re still going to be good enough to win the title and I can’t help think Deila should be allowed to have his day in the sun and hold up the Premiership trophy. But almost from the moment he places it back down he should be handed his jacket and pointed towards the exit."

"In the meantime the club can decide who they want in as his replacement. Is it going to be Davie Moyes? Are they going to invite Lenny back? Could they turn to someone like Roy Keane again, even though talks last time hit the wall? Time will tell. All I know is Deila is finished at Celtic and I’m not the least bit sad about that," he added.
