Fans were quick to react to the ex-England captain's sacking as they mocked his coaching journey so far. Birmingham fans also reminded Plymouth that they had warned them about Rooney's track record as a head coach.
An X handle named Sample wrote: "This man should just retire and return his coaching licence."
A fan named Dean wrote: "That’s Rooney's last job in football who ever appointed him deserves the sack as well."
James Hamilton advised Rooney to quit football management as he said: "If I was him I would call it a day in management and become a regular on the overlap."
A handle named Voodoo said in a message to the Plymouth board: "You had all the warnings and ignored them. Then you delayed this by at least a month, so we're literally 24 hours away from the transfer window without a coach. Absolute cluster-F."
A Birmingham fan mocked Plymouth by writing: "Why would you even give him the job to begin with? We all warned you. You seen it for yourself too?"
An X handle named AJ added: "If he ever gets a job in coaching ever again serious questions need to be asked."
