Martina is currently being played out of position at left-back but the Curacao international was still able to set up Niasse at Goodison Park on Saturday afternoon.
Niasse has now netted seven goals in 15 Premier League outings this season, and the attacker has said that "using his instinct" played a part in his latest converted effort.
The 27-year-old told the club's official website: "Cuco is right-footed and playing left-back, which is very difficult for a defender. He is trying to do his best, always. I know the guy, he is a great player and put in a really good cross. Hopefully he will continue doing that.
"When the ball is in the box, you just use your instinct. The way it is coming, the position of the 'keeper and the defenders: you have to look at all these things, then try to put it in. And that is what I did."
Everton now sit in ninth place in the league standings as a result of the victory on Merseyside.
