Martin O'Neill was disappointed after his Sunderland side could manage only a 0-0 draw against bottom club Wolves at the Stadium of Light.
In a match of few opportunities, Wolves probably had the best chance when Simon Mignolet saved from Steven Fletcher with 10 minutes remaining.
And O'Neill admitted his side had not done enough to claim all three points.
"I thought that moments of quality were few and far between," said the Sunderland boss.
"I don't think we did enough to win the game.
"We've had three games in a week but other teams have had the same.
"I just thought we looked a little jaded today - things looked like they were catching up with us.
"I think the players are disappointed because we were looking to turn things around.
"Wolves were always going to be difficult opponents; always play with spirit. But we didn't do enough, that's the bottom line."
The Black Cats' season looks to be heading for a flat finish but things looked far bleaker when O'Neill took charge back in December.
"Well, that's the encouraging thing," added O'Neill.
"The players have shown more reserves of energy and spirit than even they thought they had."
