Neil Warnock stepped down as interim Aberdeen manager on Saturday, straight after taking the Premiership club into the Scottish Cup semifinals and just 33 days and eight games into the job.
Aberdeen were Warnock's 20th team in a managerial career spanning more than four decades, including jobs at Sheffield United, Crystal Palace, Leeds United and Queens Park Rangers.

The 75-year-old replaced the sacked Barry Robson last month. Aberdeen won two cup games under Warnock but none of their six league matches, leaving them 10th in the SPL.
Warnock said his departure was a mutual decision. It came after Aberdeen's 3-1 home win over Kilmarnock at Pittodrie.
"It goes without saying that I had hoped I could have collected a few more league wins along the way but I'm also delighted to have helped the club into the Scottish Cup semifinals," Warnock said in a statement.
Robson was the fourth manager sacked by Aberdeen in the last four years.
"The Club would like to thank both Neil and Ronnie Jepson for their efforts," Aberdeen chairman Dave Cormack said.
"With the search for a new manager at an advanced stage, Peter Leven will assume control of all first team matters until the process is concluded."
