Sunderland managed to beat the Hammers 1-0, thanks to Jordan Henderson’s first goal of the season.
Ferdinand told Sky Sports: “The clean sheet was pleasing but the main concern was getting the points and a good team performance.
“The three strikers worked hard for the team, we all do, and we showed that today.
“As a team and a group we’re taking it as it comes. We’ve got Fulham next week and will concentrate on that.”
