The French forward bagged his 15th strike of the season during the Toffees' 2-1 win over Chelsea at Goodison, and insisted there are more goals on the way.
He signed a new two-year deal last week after reaching a compromise over wages with the Everton board, and feels ready to go from strength to strength.
He said: 'It's really good to have the contract talk settled.
'It was a bit stressful and I'm glad we found an agreement.
'Now I want to show every day and at every opportunity that I can work hard.
'I don't set goal targets. I just want to play most of the games and get myself in a good position to score more goals and they will come.
'The main thing is to stay at the right level.
'I signed and committed my future to the club and my aim is to do the best I can.'
Saha missed a penalty in the first half of the game against Carlo Ancelotti's table topping side, but atoned with a wonderful second half strike to give the Blues the lead.
