Wayne Rooney felt England deserved their World Cup qualification after saving two of their best performances for the end of the campaign.
Roy Hodgson's men overcame Montenegro 4-1 on Friday and produced another impressive display to beat Poland 2-0 at Wembley and reach Brazil.
Rooney opened the scoring with a header and captain Steven Gerrard eased the nerves with a late goal as England finished Group H unbeaten, and one point ahead of second-placed Ukraine.
"We're all delighted with the victory and to have qualified. It was a good group but that is 10 games unbeaten," Rooney told Sky Sports.
"I think particularly in the last two games we have played some really good stuff and again tonight, so we deserved the victory.
"The last two games were always going to be pressure games. We needed six points but we've dealt with that and put in two good performances."
Rooney's goal took his tally for the campaign to seven, but he played down the accomplishment.
He said: "It's been a good qualifying campaign for myself and hopefully that will continue, but the important thing is we've qualified."
Asked about his captain, Rooney added: "He's obviously one of our senior players and our captain, so to show that drive towards the end and get that goal which killed the game was great for him and we're all enormously pleased for him."
