Fulham striker insists Fulham's squad are united behind Martin Jol and has backed the under-fire manager to turn things around.
Some supporters called for the Dutchman to be sacked after Saturday's 2-1 home defeat to Cardiff City.
The Whites haven't won since the opening day of the season and are without a Premier League victory at home since April.
But Ruiz, who scored in the reverse against the Bluebirds, insists Jol is the right man for the job.
He said: "We are all in it together. He's having a difficult time because everybody blames him for the results.
"But we're a team and we can and will change things."
"He means a lot to me because he gave me the opportunity to come here.
"He likes to talk to the players and to motivate us, especially when we have a difficult situation."
Fulham have a massive home game with Stoke City next week.
And Ruiz added: "It's a difficult situation but the season is still young.
"Hopefully we will get a good result next week.
"It's going to be a difficult game. We know we need to win."
