Frank Lampard has admitted that he questioned his ability after England's disappointing World Cup campaign.
Lampard is determined to prove his doubters wrong
"After the World Cup I rued the fact that I had not scored any goals," Lampard told BBC Radio Five Live.
"You have to shut your ears off and not take to heart what is being said because we all doubt ourselves in certain moments.
"I had a few weeks off and now I just want to work hard. The only way you can put things right is on the pitch."
England were eliminated from the tournament after losing their quarter-final tie with Portugal on penalties.
Lampard failed to score and was heavily criticised for his performances but is determined to prove his doubters wrong.
I have always had the idea that if my level drops I could be out of the team
"The World Cup did not go right for me and in the summer people were saying this and that," he added.
"You have to be strong and in a year's time I'll look back and say 'I proved you wrong again'.
"What people do not see is that for all the stick I might get externally, I personally give the most stick to myself. I know when I have not played well enough."
But the Chelsea midfielder said that he was enjoying the pressure of playing for new England coach Steve McClaren.
England have won all three games under McClaren and play Euro 2008 qualifiers against Macedonia at Old Trafford on Saturday and Croatia in Zagreb the following Wednesday.
"That is one of the really good and refreshing things with Steve McClaren and his staff," said the 28-year-old Lampard.
"From the moment you join up with the team on Tuesday afternoon there is pressure.
"You know that you must train well, that you must be around the hotel with your mind on the game and that when the game comes you must perform at your top level."
McClaren left former skipper David Beckham out of his first squad as coach and it would seem that the Real Madrid midfielder has played his last game for England.
"This is England we are talking about, not some team that does not have young players pushing for places," said the Chelsea player.
"I have always had the idea that if my level drops I could be out of the team. The thing that keeps the top players on top is that they keep pushing themselves."
