The Dutch international left Goodison Park after close to five years on Merseyside to link up with the Cottagers in late January despite the fact the Craven Cottage are sitting deep in the relegation mire.
Heitinga has made four starts for the Cottagers since arriving and has made it clear that he does not rue his choice as he looks to keep the club in the top flight as well as force his way into Holland's World Cup squad.
"I had a few other options but Fulham was a good decision and still is a good decision," he said in the Chronicle.
"Felix (Magath) has done really well in the past with his former teams. He is a tough manager, he makes you work really hard and that is what we need at the moment.
"The main thing for me is to get [playing] time, keep Fulham in the Premier League and make the World Cup.
"I knew before I signed here that this was going to be a tough period. We know that we are in a situation where we need to win and stick together."
