The 25-year-old was one of four little-known players snapped up by Ross County from the Netherlands this summer.
So far, only young striker Kevin Luckassen has earned a regular start.
Fellow 20-year-old Marc Klok, a midfielder has yet to feature, and wide man Darren Maatsen made a spectacular scoring impact at Celtic Park only to be hooked at half-time in the defeat to Partick Thistle.
De Leeuw has had to fight for scraps from the bench, but he played well in a 35-minute run-out at Easter Road before the international break and feels fortunes will change.
He said: "It's getting better and better. I feel settled now and I know what the team want and what the gaffer wants.
"Before coming here, I spoke to Marc De Vries, the former Hearts and Dundee United striker, and he had only good things to say about Scotland. He gave me some valuable advice."
He added: "I came off the bench at Hibernian and my feeling is good. I feel ready now to give more to the team.
"In Holland, the emphasis is more on the technical side of the game, taking the ball down and playing football.
"Back home, they think of Scottish football as a bit kick-and-rush, but here the manager likes us to play. I see that every day on the training pitch and his style and outlook on the game are much the same as in Holland.
"Here it is just a little bit more physical than back home - people are harder in Scotland, basically!"
While Dutch perceptions of Scottish football may be poor, De Leeuw knows nothing will be easy at County for him and his fellow countrymen. "The four of us Dutch boys, if we want to do well, have to train hard," he says.
De Leeuw welcomes his parents to the Global Energy Stadium for the first time today for the televised clash with Dundee United. "It will maybe give me an extra boost in my performance if I play against Dundee United," he says.
