Former Republic of Ireland international striker David McGoldrick played under the 53-year-old at Bramall Lane and believes the currently out-of-work manager would be a great fit for Celtic
Wilder is just one name to be linked with the Parkhead job along with the likes of Jesse Marsch, Rafa Benitez, Frank Lampard, Steve Clarke, and Enzo Maresca with the Hoops set to appoint a new manager in the summer following Neil Lennon’s departure in February.
John Kennedy is taking interim charge of the team but a permanent appointment should be made during the close season.
Speaking on talkSPORT, McGoldrick insisted Celtic could do worse than take a look at Wilder.
"I’m sure he’ll get a job somewhere. Celtic need someone to go in there with big ideas – Wilder will go in there with his own ideas.
"He would change that club. He’d get the boys playing for him.”
