Ferguson was again outstanding in yesterday's 0-0 draw with Liverpool.
Eck said: "There's a good spirit in the dressing room.
"It's been evident there again this season, although we have got new players and we're trying to integrate them.
"As you build a team and build a club, there's more competition for places and players have to play to their very best level.
"Barry's right to say we fear nobody but we can't leave that in the dressing room."
