Celtic need to appoint a director of football if they are to have any chance of catching up with Rangers, according to Danny Mills.

Speaking exclusively to Football Insider, the former England defender claimed the Hoops’ constant success meant they became complacent and have now gone backwards.

Former Celtic manager Brendan Rodgers claimed it was “critical” the club appoint a director of football after Neil Lennon resigned as manager last week.

This site broke the news on Monday that recruitment chief Gary Penrice is set to leave the club at the end of the season.

He is likely to be followed out of the door by Nick Hammond, the director of football operations whose position is understood to be under “major threat”.

Mills told Football Insider correspondent Connor Whitley: “We’ve seen how important directors of football are. They appoint the chief scout, they appoint the manager, they appoint the coaches. They set up the structure of the club.

“They are the middle man between the head coach and the owner so it’s certainly an important role. It’s that role the chief executive used to play at a football club. Look at what David Gill was doing alongside Sir Alex Ferguson [at Manchester United]. It’s evolved since then, obviously.

“Neil Lennon was jumped before he was pushed and that loss was one too far. 

“Rangers are going to win the title and that’s obviously a big blow.

“Maybe there was a bit of ‘I’ll get out and do what I need to do before I get the sack’ which is totally understandable although I’m sure he wouldn’t have wanted to do that.

“Celtic need to have a mass reevaluation, maybe they’d got a bit complacent after nine years of success and winning things and they thought ‘we can just keep doing what we’re doing, we don’t need to change much or invest.’

“Of course Rangers over the past couple of seasons have been great, they’ve moved things along, they’ve done things a bit differently and improved dramatically.

“Celtic sort of stood still and therefore went backwards.”
