The Black Cats boss has been key to the sides chances of avoiding relegation.
The former West Ham boss has been a big hit at the Stadium of Light since replacing Dick Advocaat all the way back in October.
It has taken a long time for the Black Cats to fully adapt to his style, but the smart signings of Jan Kirchhoff and Lamine Kone have seen them improve dramatically since January.
It is fair to say that the situation would likely be much more dire if Allardyce hadn’t arrived at the club, and Murphy says he has removed the risks from their play to give them a chance.
"What Sam Allardyce has done is get the back players playing percentages and taking away the risks,” he told BBC Sport.
“They look tighter. The full backs don’t fly forward as much and playing the same people each week means communication gets easier."
Arguably the best decision Allardyce has made since his arrival was the easiest one too, putting Jermain Defoe back into his more natural central role.
The forward had been played out on the win by Advocaat and struggled to find his best form for the side, seriously hampering their chances as a result.
Under Allardyce he has shone though, with 13 goals in the Premier League to his name, and they will be hoping he can add more goals to his name to ensure their survival.
