Leeds United boss Sam Allardyce knows defensive improvement will be vital in order to keep the club in the Premier League. The Elland Road outfit are in relegation trouble and have brought in Allardyce to replace Javi Gracia - who only managed Leeds for 12 games.
It's Allardyce's first managerial job in two years, with West Bromwich Albion his last club. And the first test couldn't be much tougher, with a trip to the Etihad Stadium to take on a City side who are unbeaten in their last 19 outings.
Pep Guardiola's side are pushing for another Premier League title, with three points against Leeds the next challenge.
