Lambert scored in his first start for the Three Lions last night, becoming the first England international to net in his opening two games for 37 years in a 4-0 win over Moldova.
He told Sky Sports News: "I obviously wanted to try my best to help the team and I am hoping to give the gaffer another option as a striker.
"That is what I was trying to do, to impress again, and to score a goal again for England is superb. I was overjoyed to get my first start for England and for it to have gone like that again, it is terrific.
"Obviously it is going to be a different game again on Tuesday, we know that, and whatever role is in there for me, I am more than ready for it."
The 31-year-old was joined on the scoresheet against Moldova by Steven Gerrard and Welbeck, who bagged a brace despite the disappointment of that early booking.
