With the Steve Bruce being the first managerial victim of the season, attention has quite naturally shifted to who his successor will be. The football world works fast and quickly and it did not take long for the club to reveal that the man to fill the seat of Steve Bruce will be Martin O’Neill, who has been Aston Villa and Celtic manager just to name a few.Biggest challengeO’Neill does not come into a simple role, the biggest challenge that he will face will be trying to create some stability for the future, achieving this will require planning and a great deal of hard work. Luckily for Sunderland O’Neill is one of the better managers around and the future of the club could not depend on a better manager.The one factor required for the club to be successful, is the necessity of continuity on the pitch, they already possess a decent stadium and fan support second to none. One of the greatest problems that the lesser Premiership clubs face is their ineptness of keeping faith with the same manager.Not keeping the same manager of a team means that with every new manager comes new players, which obviously means the team will always be changing instead of staying the same and being given the chance to develop.The problem Sunderland have had is that since their promotion from the Championship to the Premiership in 2007 they have had 78 different players, this is much more than any other team in topflight football in England. As such it is no surprise that their form has also struggled since move up.The reality is that only three players from the 2007-2008 season remain, Kieran Richardson, Phil Bardsley and Craig Gordon , the first two coming from the Manchester United system and funnily enough so did their last manager.11 new playersAnother interesting fact over why the team from the north have struggled is that every player that has finished as top scorer has gone on to leave the club, players include Kenwyne Jones, Djibril Cisse, Darren Bent, and Asamoah Gyan.This summer despite finishing 10th, Sunderland have gone on to sign 11 new players, the club is therefore getting a reputation as a place to go to get seen and then move to a bigger club or as Asamoah Gyan did move for money.As such the club requires a strong headed manager who can affect change into the clubs practices and get the most out of the players that are currently there.
