With no concerns over the calf problem, Vermaelen insists he is ready to step into the starting line-up for their Premier League clash with Chelsea this Saturday.
"I feel great," Vermaelen told Arsenal's official website.
"I trained with the team and I felt good straight away so I felt confident.
"Personally I don't believe in that [needing games to regain sharpness]. If I come back from injury after a long time I don't believe in coming back and getting rhythm.
"I think it is just in your head and a mental thing - if you are a football player you have to be there straight away. That's why I wanted to play today and I think it's good.
"It was a good game for us, we fought hard and it was a deserved win for us I think."
