The 33-year-old was kicked out of the national team by previous Poland head coach Franciszek Smuda for his behaviour on the plane back from a US tour.
And his career at Southampton began in controversy when the keeper was alleged to have thrown a water bottle into the crowd on his home debut against Tottenham at St Mary's.
But ahead of Poland's friendly against the Republic of Ireland in Dublin on Wednesday, Boruc claims he has 'grown up' and has high hopes for the future as Saints No.1.
"I've matured over the last few months," he told Polish news organisation Sport. "I was determined to get back in Southampton's goal.
"I lost my place. The Tottenham game ruined my plans but that was only a one-off incident.
"I hope I've earned my call-up. I've been told I have a clean slate from the new coach.
"I've grow up and matured. I always wanted to play in the Premier League, though I hoped to make it here earlier.
"Goalkeepers are usually better with age so there is still some time ahead of me."
