Narsingh is weighing up a loan move away in January.
WalesOnline says Narsingh is being linked with a January exit as Fenerbahce reportedly weigh up a loan move for the Dutch international.
The 27-year-old was the first signing of the Paul Clement era when he joined from PSV Eindhoven in a £4million deal in January 2017, although the Swans had been keen on securing his services for some time prior to the head coach's arrival.
Meanwhile, Romanian youngster Marco Dulca was delighted to start for the U23s in defeat to Manchester United - his first of the season.
“I'm very pleased with my performance and to have made my first start, so I will take a lot confidence going forward," Dulca said.
“Obviously, I want more chances this season. I am still only 18, so when my chances do come I have to make sure I take them and put in 100 percent.
“Saturday was an important game for us and I think the boys put a shift in.
“We played very well in the first half, but when United scored our performance levels dropped a little bit and they got the second goal which killed the game."
