Obita has caught the eye during Oldham's FA Cup run, which ended last night at Everton.
"I think I'm showing I can play well against the top teams," he said. "Everton are a top-six side in the Premier League. In the last game I thought I did very well against an ex-England international in Phil Neville.
"I'm not doing it for a top club, I'm doing it for a League One club so I think that can show Reading I can do it in any team."
