Luis Suarez and Henderson gave the Reds the advantage by the hour-mark before Olivier Giroud and Theo Walcott responded for the Gunners and although it was an opportunity missed, the midfielder was pleased with the result.
"It was a good game of football. I thought we played well at times but we had a spell when they scored two goals when we were under pressure," he told Sky Sports.
"But overall I think we've got to go away positive, it's a good point - Arsenal are a good team.
"I think we've got to be happy but having gone 2-0 up, we're a little disappointed to have conceded two goals so quickly."
