Modric insists he still values his time with Spurs.
"My one regret is that I didn't win a trophy with Tottenham, despite us being a strong team who played good, attractive football," he told FourFourTwo. "I'm sorry for the way I left. I wish we had parted in a nicer way. I hope fans understand that I followed my dreams.
"I had a fantastic relationship with the people at the club, and also the fans. The whole atmosphere in and around the club at that time was brilliant, and our results were mostly very good.
"We played in the quarter-finals of the Champions League, against Real Madrid, and in a League Cup final too."
Modric added: "Do I still follow their results? Yes, when I have time. I always enjoy watching Tottenham's games and I really like what the club has become over the last few seasons."
