Gianfranco Zola was refusing to be too downbeat despite watching his West Ham side fall to a 2-0 defeat against Manchester United.
The Hammers have now lost four games on the bounce in the league and are in real danger of becoming embroiled in a relegation scrap this season.
Cristiano Ronaldo's first-half brace was enough to put United in complete control and at no point did West Ham look like reversing the situation.
West Ham did improve after the half-time break, after what was an uninspiring first 45 minutes, and Zola is keen to draw on such a positive.
"The second half has to be a starting point for us," said Zola, whose side tackle Middlesbrough at the weekend.
"It is very important for us to pick something up on Saturday and stop this losing run.
"I have total belief in the players. I have so much faith in their quality and I am sure they will soon get over this bad spell."
Zola went on to report Valon Behrami had been stretchered off with a major calf injury that will rule him out for a lengthy spell.
