Allardyce was appointed as Sunderland boss back in October, and it has not taken long for him to make an impression on Wearside.
The 60-year-old boss has inspired a remarkable improvement in the Black Cats’ form, and he has managed to guide them out of the relegation zone for the first time this season.
Coates has been very impressed by Allardyce’s methods so far, but the Uruguayan defender knows that his side are not entirely out of trouble yet.
“He is working well for us. Everyone knows that as a former defender he is perfect for us – and he is helping me,” he said.
“We are a more compact side under him, we are playing more like a unit.
“It is important, though, that we keep improving.
“We still have plenty of work to do.”
The biggest improvement that Allardyce has made at Sunderland has been in the side’s defence.
The Black Cats looked particularly porous during the opening weeks of the season, but they now look robust and well organised.
Sunderland have won their last two fixtures – against Stoke City and Crystal Palace – and in both those games they have kept clean-sheets.
The turnaround his been nothing short of remarkable, and it seems that Allardyce’s proud record of never being relegated in his managerial career is set to continue.
