Captain Lorik Cana insists free-falling Sunderland are good enough to retain their Premier League status.
The Wearsiders saw their winless Premier League run extended to 13 games after losing 2-0 at Arsenal on Saturday.
The Black Cats have plummeted from the top eight down to their current 14th place in the table, but Cana believes their fortunes will improve when manager Steve Bruce is finally able to name his first-choice line-up.
Combative midfielder Lee Cattermole will return from suspension for Saturday's visit of Fulham to the Stadium of Light.
"The players that came in against Arsenal did well, but we have Catts back for the next game and that is so important," Cana told The Journal.
"I really believe that when we have our strongest XI, we can do well against any team in this league.
"Having me and Catts on the pitch for the rest of the season is very important.
"The manager has told us that this is the time for us to show great spirit. I agree with him and think that we showed that against Arsenal.
"If we take that mentality into these next four or five home games, then I am confident we will be okay.
"I am a fighter, I never give up, but I think we have a team who have great fighting spirit."
