Pressure on Mancini to win derby
Roberto Mancini faces an end-of-season review led by chairman Khaldoon Al Mubarak as City check they've got the right man for the job.
The Italian will travel to in Abu Dhabi to pick apart the season with the chairman, chief executive Ferran Soriano and director of football Txiki Begiristain.
Only one of the two managers in opposing dugouts at the Manchester derby tonight will be analysed this way, increasing the pressure on Mancini to beat Sir Alex Ferguson's side again at Old Trafford and bring the FA Cup back to the Etihad Stadium in May.
If United beat City tonight and Mancini's side are then knocked out of the Cup, the former Inter boss' situation would be weakened.
Mancini was given a five-year contract last summer to indicate the faith Sheikh Mansour has in him and the club will not press the panic button because they embrace stability.
However, with City 15 points behind United in a disappointing championship defence and the failure to reach the Champions League knockout stages for a second successive year - the team finished bottom of their group - there remains doubt over Mancini's position.
