Germany's Thomas Mueller has recovered from a head injury and is ready to face the United States in the final group match at the Arena Pernambuco on Thursday.

Mueller suffered the injury after a nasty clash with Ghana defender John Boye in Germany's last group game and ended up on the turf, but the Bayern Munich striker has insisted that he is now alright and has clear vision in the left eye.

"Thanks for the many well wishes," Mueller wrote on his Facebook account. "All good with me, even if I look a little like a boxer. Do not worry, I'm well again. My cut was expertly sewn from Doc after playing with five stitches, so I already have a clear view, even if the eye is still a little green and blue."

"On Thursday we enjoy a tough match against the USA. But what is clear: We want to be first in the group! And with your support we will make it!"

Germany was held to a 2-2 draw by the Black Stars in the last game, after they thrashed Portugal in the opening fixture. Both the US and Germany need just one point to seal a Round of 16 berth, but the 24-year-old stressed that the team is looking to continue its form in the remaining fixture.

"We want to finish top of the group," Mueller said. "Six goals in two games is not bad. We could have scored more against Ghana and also against Portugal. We still always want more and more."

"Joachim Low has left his mark on this team," he added. "The most important thing is we walk step by step, one game at a time."

Mueller, who finished the joint top-scorer in last world cup with five goals, is also in the race to  win the Golden Boot award, after scoring a hattrick against Portugal in the first match. However, the star striker said he is concentrating on winning the World Cup not the Golden Boot.

"I won the Golden Boot four years ago and, to be honest, I wouldn't know where to put another one," he said. "It is never my goal to be the top scorer, but rather to be world champion. Of course, it's nice to see your name at the top, but that's no big deal. There is another title which is far more valuable."

Mueller said Germany will continue playing possession-based football in the upcoming matches and they will go hard at their opponents to make them uncomfortable .

"Every team who comes up against us has to swallow hard," he added. "That was our aim - we wanted to be uncomfortable opponents. We're not a team who play long balls. That's not our style. We like to have more possession and I think we're heading in the right direction."
