The Dutchman faces a tough task in trying to keep the Black Cats in the Premier League in what is his first job in English football.
Sunderland have won just four league games all season and are without a win in six following last weekend’s shock 4-0 defeat at home to fellow relegation strugglers Aston Villa.
Advocaat has plenty of experience as the 67-year-old has managed at eight different clubs from the Netherlands, Russia, Germany and a four-year spell with Scottish side Rangers from 1998-2002.
He has also enjoyed international coaching roles with six different nations and has managed his homeland on two separate occasions.
Advocaat will become the oldest manager in the Premier League and will hope his wealth of experience can prove valuable.
He has an average win percentage of 54.5% through his coaching career so far and if he can transfer that record into the final stretch of Sunderland’s season, the Black Cats will more than likely be safe.
It must be noted that this is simply a projection based on the previous successes Advocaat has enjoyed. A projected final tally of 40 points would surely be enough as no team has been relegated with a minimum of 40 points for the past 11 seasons since West Ham were with 42 points in the 2002/03 campaign.
The task of turning things around at Sunderland in the middle of a fierce relegation fight is a new challenge for the Dutchman but he will hope his experience can help to make an immediate impact.
A tough end to the season will see Advocaat and his new team travel to West Ham this weekend, while tough away trips to Arsenal, Stoke, Everton and finally Chelsea on the final day of the campaign also lie in wait.
To pick up the projected 14 points, Sunderland will need to win at least three of their last nine but it will likely need to be more unless they can draw their other six remaining matches.
Home games against rivals Newcastle, followed by Crystal Palace, Southampton and Leicester will all be seen as winnable by Advocaat and he must now turn all attentions to fixing things quickly before Saturday night’s trip to West Ham.
