Sean St Ledger is desperate to make up for lost time as he attempts to force his way into the Ireland team for Saturday night's Euro 2012 qualifier in Macedonia.
The 26-year-old has been out of action with a knee injury since the middle of March and just last week was not even in the frame to play in Skopje.
Asked what he had told Trapattoni about his fitness, he said: "I told him I'm fit and I want to play. I want to play for my country. I love playing football, whether it's in a park or... I watch all kinds football on TV."
St Ledger's condition has improved so rapidly that manager Giovanni Trapattoni is now considering him as a genuine option to return to a defence deprived of the services of stalwart Richard Dunne through suspension.
He added: "I want to play football as long as I can. I've been playing for eight years. It's something I love and there's only a few years left.
"It's a great profession to be in. Every kid wants to do this."
