The 22-year-old set up the Three Lions' opening goal and rounded of an impressive performance by scoring one himself in Friday's 4-1 win over Montenegro in 2014 FIFA World Cup Brazil™ qualifying. The result left England needing to beat Poland at Wembley on Tuesday to be certain of a place at the global finals.
"It hasn't sunk in at the moment and I haven't allowed it to because we've got another big game on Tuesday," Townsend told Tottenham Hotspur's official website after his surprise selection by England manager Roy Hodgson. "That's the best thing: to keep my feet on the ground and try not to get carried away."
"No matter who I'm playing against, I look to play the same way. I look to take people on, make things happen and try to get my shots off. It all came together. It couldn't have gone any better."
Redknapp raves about Townsend
Townsend has established himself at Tottenham this season after several loan spells, including one at fellow London side Queens Park Rangers. QPR manager Redknapp, who was in charge when Townsend was trying to break into the Tottenham first team and took him on loan to Loftus Road last season, believes the player is the nearest thing in the England squad to Dutch star Arjen Robben.
"If he can keep improving, I think the sky's the limit," Redknapp said. "It's up to him now. He's got a great chance.
"Andros is not Arjen Robben. He's not in his class at the moment, but he's very similar. He plays on that right side, likes to come in on his left foot when he can, he runs with the ball, he beats defenders, he tests the fullback."
Reflecting on why Townsend had spent so much of his recent club career away from White Hart Lane, Redknapp added: "We loaned him out an awful lot because he couldn't get that consistency. He'd have a great spell for four or five games with a club and then his form tended to dip a bit.
"I brought him to QPR last year and he sustained that run of form throughout. That was the making of him. He proved he could play Premier League football week-in, week-out and could do it consistently well."
