A month ago Sir Alex Ferguson was in charge at Manchester United, Roberto Mancini was hoping to win his second FA Cup final with Manchester City and Rafael Benítez was yet to lift the Europa League trophy with Chelsea. Now they are all gone and three new (or not so new) managers are ready to take their places.

David Moyes went to work at Manchester United on the day after Ferguson watched his side draw 5-5 with West Brom; José Mourinho has joined Chelsea on a four-year contract; and Manuel Pellegrini has a verbal agreement with Manchester City.

There was a time when United fans expected Mourinho to take Ferguson's job, City fans wanted Mancini to stay and Chelsea fans hoped for nothing other than Benítez to leave their club alone.

Football can be an unpredictable business, but who do you think will prove the best managerial signing of the summer?
