Williams told BBC's Football Focus: "For the West Ham fans and the club they want to see a hard-working team and a bit more bravery in possession.
"Under Potter, it was flat - there was nothing for the fans to get behind. Nuno can galvanise the club and he is the perfect person of the available managers to put in there.
"West Ham have been so easy to play against. You only have to get out of second gear to beat them.
"Nuno will organise his team and figure out what players he wants and what players he can work with."
