The Swans have turned their season round recently with Sigurdsson's form pivotal in their renaissance.
The Iceland international scored the winner in the fantastic home win over Chelsea on Saturday, and took his tally of goals in the league to 11 as a result.
Bony scored 25 goals in the Premier league for the Swans, and Sigurdsson told of his pride at equalling that record:
"I had been told I was getting closer (to Bony's total) and that has driven me on a bit. It is a great achievement and I'm happy to be up there with Bony as he is a very good player. Hopefully I can get the next one by the end of season and get one over Bony."
Swansea have been on a fine run of form since the arrival of manager Francesco Guidolin, winning six out of 12 matches in the league, while only losing three.
The Welsh club's good run has coincided with Sigurdsson's own form improving in the second half of the campaign.
He spoke of his improvements since January, highlighting his impressive goal return adding:
"I probably wasn't too happy with myself before the turn of the year. I'd only managed two goals, but it's been good to score goals at an important time of the season. I'm very happy getting into double figures."
Swansea's win over Chelsea on Saturday took them on to the magical 40 point mark, and a full 13 points clear of 18th-placed Sunderland with little football left to play.
