Wenger agreed and believes Henry is still more than capable of making an impact.
He said: "England defended well but I would say it was hard for both sets of strikers.
"But the tournament has just started. He will still have a big part to play for France, I am confident of that. Both teams were set up in similar fashion, with a wide left player who tucked in. That left nobody on the left to help the front players."
Wenger then gave his early reflections on the tournament and nominated Italy as the most disappointing team to date following their tame performance in a goalless draw with Denmark.
"But you have to also remember that Italy often start slowly and get better as the tournament goes on," he said.
"They were not too impressive against Denmark but you would not be surprised if they got better in the games to come.
"What I would say, however, is that the two worst defences I have seen so far are those of Bulgaria and Russia.
"Sweden looked good when they beat Bulgaria 5-0 and they looked stronger than everyone expected. But I don't know how much that was because of Bulgaria's poor defending.
"Spain looked compact and looked capable of picking up the momentum but, again, they were up against a poor Russian defence."
