Alex McLeish has claimed the new Celtic manager needs to copy Sam Allardyce by signing a “certain type” of player.
The former Scotland boss, speaking exclusively to Football Insider, suggested Neil Lennon’s replacement would already have new players in mind.
The Northern Irish boss resigned from his post last week after a disappointing campaign at Parkhead.
The Hoops were knocked out of Europe at the group stage and have watched Rangers storm ahead in the Premiership title race.
The Bhoys’ recruitment has come under fire from fans and pundits, with the likes of Shane Duffy and Vasilis Barkas heavily criticised.
McLeish suggested a new manager would need to turn things around by bringing in specific players at Parkhead.
However, he warned they would need to be both mentally and technically up to the challenge.
“When a manager comes into a job as high as the Celtic job, he will have players in his mind that he will be wanting to bring,” McLeish told Football Insider’s Russell Edge.
“You’ve seen over the years Big Sam Allardyce doing some miracle jobs in England, keeping teams up. He buys a certain type of player.
“Therefore, the new Celtic coach should be having to buy a certain type of player.
“Some he knows can be mentally good and technically good enough for Celtic to compete with Rangers.”
John Kennedy has been put in temporary charge of the Bhoys following Lennon’s departure.
The long-serving coach won his first game 1-0 against Aberdeen last weekend.
