Spurs boss Harry Redknapp has already rejected a £22million bid from Chelsea for the playmaker.
Manchester United and Manchester City are also reportedly interested in the midfielder.
“If somebody comes to the club and the offer is good for me and acceptable to them, then I want to leave,” Modric is quoted by the Daily Mail.
“I want to leave Tottenham as friends. I have enjoyed my time there, but now it is right for me to look at another club.
“I have an arrangement with the chairman. When I signed my new contract, he said that, if another club came to sign me, they would consider the offer.
“I won’t ask for a transfer, no. That would be disrespectful. I hope they can reach an agreement that is satisfactory for everyone.
“Chelsea are a big club with an ambitious owner. They have great players and they have ambitions to fight for the title and win the Champions League. I want to stay in London. I am very happy here and so are my family.”
“I don’t want to have an argument with Tottenham. The supporters have been very good to me and I have enjoyed my time playing for the club, but it is for football that players leave clubs and move,” he added.
“It has happened to Tottenham before. It is normal for a player to dream about playing for a bigger club.”
