Daniel Sturridge is in line for a place in England's starting line-up against Germany at Wembley on Tuesday after recovering from the thigh injury that ruled the Liverpool striker out of the defeat by Chile.
Sturridge is expected to partner Wayne Rooney up front as Roy Hodgson's side attempt to restore morale after Alexis Sanchez's goals condemned an experimental England line-up to a disappointing 2-0 friendly loss at Wembley on Friday.
"I had a lot of treatment over the last few days," Sturridge told reporters at England's hotel in Watford, north of London, on Sunday.
"I have been working very hard to make sure I am OK. I am going to go out on the training field today and I am raring to go for the game.
"It was very frustrating (not to play on Friday). It is important for me to be fit and play for England," insisted Sturridge, who has scored two goals in his eight international appearances.
The 24-year-old added: "It is not a serious injury so I am hopeful it doesn't continue to linger on.
"I have been playing with it for the last couple of games and it has been hindering my performance.
"I had a scan and the scan showed it was similar to what it was before. It is not a problem for me - I am raring to go for the game. I am delighted that the pain is not as bad and I am looking forward to it."
With the months ticking down towards next year's World Cup finals in Brazil, Sturridge said the England players were under increasing pressure to impress manager Hodgson.
"There are two games now before the manager selects his squad and it is important everybody stakes their claim and nobody is taking that for granted.
"It is important to work hard at your club, play well at your club and when the opportunities come to play for England, you take them and just try and stake your claim to go to the World Cup."
The Chile defeat deflated some of the optimism generated by England's success in qualifying but Sturridge insists the meeting with the South Americans would prove invaluable to Hodgson's side's preparations.
The forward said: "I think we always knew they would be difficult. We knew that they are a very good team, the way they pass the ball and they have got very good individuals.
"We knew before we got into the game that that's the kind of they would have played. I think they won the same amount of games as Argentina in qualification so they are a very good side and we knew that.
"Looking back on it now, we will have a look at the videos from the game and I am sure we will reflect on what we could have done better and what we could have improved on."
The historic rivalry between England and Germany means this week's friendly carries an extra edge but Sturridge said: "Every game that we play in is going to be important for us, not just whether it is Germany.
"I am sure it will be a tense game and everybody will be looking forward to it. I am certainly one of those players who is looking forward to it."
