Fulham manager Martin Jol admits two back-to-back London derbies could determine his future at the club.
The Cottagers are in the Premier League's bottom three after five consecutive defeats and play fellow strugglers West Ham on Saturday before facing Tottenham on Wednesday.
Asked if his position was safe, Jol said: "If we win, yeah. If we don't, I don't know. It's always difficult.
"If I was on the board or an owner I would be worrying. We need wins."
Fulham have earned 10 points from 12 matches this season and have won just once at Craven Cottage, leading some fans to criticise Jol and his players.
Jol, who joined the club in June 2011, added: "You don't have to talk to an owner to be aware of the fact that you need points to get back to a winning culture, to a little bit of stability.
"You can lose once or twice but you can't lose four or five times on the trot. That will put you in a bad position.
"One win will get us back among others and take the pressure off and then hopefully we could have a good run like last year."
West Ham are one place above Fulham in the table, with goal difference separating the two sides, and Jol said he wanted to promote a sense of unity to get the fans back on side.
"It's not about me, it is about us," ex-Tottenham manager Jol, 57, said. "It's a big week because if we could manage to win two games we would be fine.
"My message is you have to back the players. If you talk about [strikers] Dimitar Berbatov or Bryan Ruiz, they are different they are skilful players, but they are giving 100%, believe me, even though they look a bit different.
"I feel it is trust and belief needed by the fans that they will do their best for the club. After the match it does not matter if they boo them off the pitch, or me, but during the game we need support.
"There is always pressure and you have to set your targets. We talk about targets with the players. Our target is to get enough points to be over 20 points after Christmas."
Earlier this month, the club appointed former Manchester United coach Rene Meulensteen as head coach to work alongside Jol.
And the Fulham boss said of his fellow Dutchman: "Sometimes you have to change something to get back to winning ways and I thought it was necessary to get someone like him and I think it has paid off in training.
"The players have responded to it and some have got a new lease of life.
"We are not a typical club with problems. There is a good atmosphere and spirit, a good rhythm too in training. I feel we are good enough to get higher up the league."
