"I'm pleased for Theo and the team, and I am happy to be here with the squad, but I don't expect to play in every game anymore," said former 33-year-old England captain. "That's the way it is now.
"I was happy to get on in both games [Andorra and Croatia] and would have liked to have played more but it's all about the team and the squad, and qualifying for the World Cup.
"I really don't care if I play or not. I'm just happy with the way they played and with the six points from the two games. The biggest thing is England winning and qualifying."
