The Serbian coach is under pressure following an awful start to the 2013-14 season, but he believes that one win can help turn the team's fortunes around
The 47-year-old came under further pressure after watching his side fall to a 3-0 home defeat to Swansea in the Europa League on Thursday.
This result came off the back of three successive losses in La Liga and means Valencia have now conceded three goals in their last four matches.
However, the Serbian coach remains confident he is the right man for the job, and has backed his side to come out fighting when they host Sevilla on Sunday.
"I look at this with strength," he told reporters. "It's the same as always. I will not resign.
"We [the coaching staff] all agreed that we lack confidence and that we can start resolving this with a win."
