The QPR striker recently suggested that most of the Cottagers' players do not like their manager, but the Dutchman has moved quickly to dismiss the claims
Zamora was sold to QPR in January of last season after reports suggested his relationship with the 56-year-old had soured.
And Jol dismissed the accusations before hinting at the attitude problems which seemingly led to the Englishman's exit from Craven Cottage.
"It is probably sour grapes," Jol told the Evening Standard.
"I think nothing is what it seems. Everyone knows me. The players know me so one player will say this, another player will say that.
"It doesn't matter. I don't care. For me, the most important thing is we get the results so you will have to ask the players.
"If they do well and work hard, I try to get a good relationship with them. If not, I don't. Insiders here know that this probably started after two weeks of me being here.
"There was a few leaks in the paper and I asked him and he said 'no, it wasn't me'. I knew it was him and his agent 100 percent.
"He said 'no, it wasn't me, I hate the press'. He hated defence and later said he hated crosses as well and that was the moment I thought 'maybe it is better to sell' and that is what we did."
Zamora was the first of a number of recent high-profile departures from Craven Cottage, but the Fulham boss insists he has no issue with many of his former players.

"Mousa was phoning me after his move and thanking me for everything. Every player is different.
"Clint wanted to move so then the relationship would not be great. Danny Murphy I wanted to keep so ask him. There were no issues at all.
"With Bobby it started after a couple of weeks. Everybody knew and now he has moved on. I don't think it is typically English to make comments after year or eight months.
"We moved on and it was not easy because I had to get another number nine. We did because (Pavel) Pogrebnyak scored as many goals in a couple of weeks as my other strikers did in six months.
"Later we got (Dimitar) Berbatov, who was probably our best signing ever, so people who know us, know Fulham and know me, knew it was quite a challenge here. In hindsight, you could say we managed to do well."
Fulham also announced the signing of the out-of-contract Senegalese midfielder Mickael Tavares on a short-term deal on Friday.
