The 32 year old made his Swansea comeback last Saturday against Watford as a substitute, and produced an impressive display.
He did miss a glorious opportunity to level the scores before Alan Tate’s last minute equaliser, but still brought something different to the Swans team in the second half.
Bristol City are believed to be looking for a fee as low as Â£50k for the release of Trundle, which could tempt boss Paulo Sousa into making the deal permanent come January.
“All the fans that I have met since returning have been brilliant with me and to run back out on Saturday was a great feeling,” he told Sky Sports.
“I had a little chance before we got the last-minute winner with a header that I put wide, but to snatch a late equaliser was the icing on the cake really and it was important not to lose going into the international break.
“We put a lot of pressure on them in the second half, so I felt we deserved a share of the spoils.
“I’m 100 per cent focused on sealing a permanent return to Swansea and I have never ruled out returning here because it is a club that I love and that I spent my best years at.
“I am a confident player and hearing the fans sing my name before I had even kicked a ball on Saturday was great. I’m the type of player that likes to go out and entertain and hopefully I can do that again for these wonderful fans.”
