Baines hailed the Tottenham winger.
"It was a great performance and it was a massive lift for us," he said.
"It was great for him to score that goal and he is now an important part of the squad who can produce match-winning performances."
Baines added the introduction of young talent such as Townsend along with the experience in the England squad put England in good shape heading towards Brazil, provided they qualify.
He said: "We have fresh blood and excitement - combined with the experience of other players - and that mix puts us in a great position to go there and try and do something there."
