The skillful Dutchman was sent on loan to the Rotterdam club at the beginning of the season and has scored four goals for the Eredivisie leaders.
Watford can recall the winger this month because of a clause that was inserted into Berghuis' season-long loan agreement – and that prospect looked likely after Walter Mazzarri's squad was ravaged by injury.
But Berghuis admits he's in the dark over a sooner-than-expected return to the Premier League and wants to further contribute to Feyenoord's title tilt.
"I'm the same as all those people. I have also read, but I have heard nothing further from Watford," Berghuis told RTV Rijnmond.
"That is an option, yes. But it's totally not discussed or mentioned. I haven't even thought about it.
"I'm getting playing time and [we could] become champions," he said. "We do well and I myself also picked up. I feel good. We have one goal and everyone wants to achieve that goal."
