Keane has endured a frustrating season after falling out of favour at White Hart Lane, with a loan spell at West Ham being hampered by injury and ending in relegation.
The much-travelled 30-year-old has now linked up with the Republic of Ireland for their four summer fixtures but is not viewing them as a chance to parade his talent to prospective new employers. Keane, who has already played for eight clubs, said: "I will just concentrate on doing what I do and hopefully score goals."
He added: "It has been a frustrating season for me but that is the past now. I will concentrate on these four games, take a break, switch off from football for a few weeks and then go back and see what happens. I have only got one year left there [at Tottenham] so I am sure they will probably want to do business on me."
West Ham do not want to re-sign Keane following their relegation to the Championship but he would prefer to stay in the Premier League anyway - if any clubs express interest. Newly-promoted QPR have been linked but have not made any interest official.
He said: "The chances in the Premier League for me are fairly slim. For me it is about enjoying my football and playing as much as I can, maybe going to a team where I can maybe help the younger players that are coming through.
"I am not getting any younger but I will go back and see what happens. I am a Tottenham player and I am sure they will want to get a bit of money for me. Whether a Championship team would pay that, that's another problem, but I want to play in the Premier League for the next couple of years."
Having overcome a calf injury, Keane is hoping get back to full match fitness for Ireland's Euro 2012 qualifier in Macedonia on June 4. He will captain his country in Tuesday's Carling Nations Cup game against Northern Ireland in Dublin but is only likely to play the first half.
He will then hope for more action against Scotland in the same competition on Sunday. Keane, Ireland's record goalscorer with 46, said: "I am really looking forward to being with the Irish team, switching off from the Premier League and helping this team get three points against Macedonia."
Keane did not train with the rest of the squad having been invited, as captain, to meet President Barack Obama during his state visit to Dublin. "It's a great honour to meet the president, an absolute pleasure," said Keane at his pre-match press conference. "It's a bit surreal but I'm looking forward to it."
