Leicester have appointed Craig Shakespeare as their new manager until the end of the season after Claudio Ranieri's dismissal last month.
He has won his first two games as caretaker for the Premier League champions, to take them out of the relegation zone, as they battle against the drop.
Here, Press Association Sport looks at some previous caretaker and interim managers who went on to have brief or major success.
Eddie Howe (Bournemouth)
Howe became the Cherries' caretaker boss at the end of 2008, after Jimmy Quinn's exit, taking the job permanently in January 2009 at the then League Two club.
As the youngest Football League manager, at 31, he steered Bournemouth to safety - despite having been deducted 17 points at the start of the season after they failed to exit administration.
The Cherries were then immediately promoted the following season - before Howe joined Burnley in January 2011.
A return to the south coast came 18 months later and he guided Bournemouth to promotion to the Championship in 2013 and then the Premier League, where they have remained, in 2015.
Garry Monk (Swansea)
The 38-year-old - now rebuilding Leeds as promotion chasers in the Championship - took over as caretaker manager at Swansea when Michael Laudrup was sacked in February 2014.
He was the club captain and guaranteed the Swans' Premier League safety that season before becoming permanent manager in May 2014.
Monk earned plaudits for taking Swansea to their highest ever finish - eighth in the top flight - a year later but left the Liberty Stadium in December 2015, ending his 11 year association with the club.
Roberto Di Matteo (Chelsea)
The Italian, already a Chelsea hero following his playing days, was first assistant to Andre Villas-Boas and then caretaker manager after the Portuguese was sacked in March 2012.
One of his first achievements was to overturn a 3-1 first-leg loss against Napoli in the Champions League last 16 - winning the second leg 4-1 in extra time.
Chelsea advanced to the last four by beating Benfica 3-1 on aggregate before a 3-2 semi-final aggregate win over Barcelona.
A penalty shoot-out against Bayern Munich secured Chelsea's first Champions League trophy but it all ended in tears for Di Matteo as he was sacked in November 2012 with the Blues third in the Premier League and on the brink of a European exit.
Rafa Benitez (Chelsea)
The Spaniard was never universally popular at Stamford Bridge but he at least delivered the 2013 Europa League title.
Following the sacking of Di Matteo, Benitez was appointed interim manager until the end of the season and eventually finished third.
Chelsea had been knocked out of the Champions League, eliminated despite a 6-1 victory over Nordsjaelland under Benitez, to enter the Europa League.
Victories over Sparta Prague, Steaua Bucharest, Rubin Kazan and Basle sent them to the final where Branislav Ivanovic's last-minute header gave them a 2-1 win over Benfica - before Jose Mourinho returned in the summer.
Mario Zagallo (Brazil)
In the run-up to the 1970 World Cup Joao Saldanha was sacked and Zagallo put in place to manage the talents of Pele, Jairzinho and Carlos Alberto.
Brazil claimed their third title, allowing them to keep the Jules Rimet Trophy, after a 4-1 final victory over Italy in Mexico.
Zagallo got the job on a permanent basis until 1974 and helped Brazil win the 1994 World Cup as assistant manager before becoming boss again until 1998 - when they lost the final to hosts France.
He won 110 of his 154 games, drawing 33 and losing just 11 times.
