The Chelsea star started his first game of the season in Sunday's 2-1 win over Newcastle although spent half the match on the floor due to the home team's physical tactics.
After playing the full 90 minutes, Hazard said: “The Premier League is always like this - every weekend is the same.
"But I'm not complaining, I try to do my job and when you have the ball, you get kicked so no complaints. You just try to play better.
“I felt tired after the game but, at the end, I was happy with the result and the goal. When you win games you forget that you are tired so now we have one week to rest and be ready for the next game.
“We need to keep this momentum. We want to be at the top at the end of the season.
"We know the League is not finished and it's just the beginning - but the confidence is coming and the goals are coming."
On the result, he added: "We spoke at half-time about this kind of game. We said that if we are in control, then we can score at any time so I think we just needed to keep the ball, keep possession and didn't try to go too quickly up front or with our shooting and when we got the chance we needed to score. That's what we did."
