Sam Allardyce will make his debut in the dugout when Leeds United travel to Premier League table toppers Manchester City on Saturday afternoon.
The 68-year-old replaced Javi Gracia as manager on Wednesday after the Spaniard was relieved of his duties following a run of just three wins in 11 league games.
Leeds lie in 17th place and are only separated from the relegation zone by goal difference. Allardyce has the unenviable task of rescuing them from the drop with four games remaining.
