The England U21 international impressed in the 1-0 win.
"It is always nice to play, I am sure that is the same for everyone," Henderson said.
"But we are a squad and there will be times when other people come in and I have to keep fighting for my place and hopefully stay in the team.
"The most important thing in your first game of the season at home is to win the game and that is what we got."
