Luka Modric has shrugged off his slow start at Tottenham by insisting he was 'always confident' of being a success at White Hart Lane.Signed by former boss Juande Ramos at the end of last season, the 23-year-old struggled for form as Spurs began the campaign in dismal form.After picking up just two points from their first eight Premier League games the Spaniard ultimately lost his job with the Croatian international coming in for criticism with fans claiming he was too small for the robust nature of English football.But ever since current manager Harry Redknapp took over the reigns at White Hart Lane Modric has become an integral member of the team with the former Portsmouth chief shaping his side around the little Croatian."Everyone has a different view on football but I didn't have a fear that I wouldn't be good enough in England," Modric said."I believe in myself and my quality and I think I've proved that I can play here. I think I'm playing better and better."All my career, people have asked if I'd be strong enough and that started when I went to play (on loan) in the Bosnian League and then in the Croatian League and even for the Croatian national team."A lot of people wondered if I would be able to do it but it's never bothered me. It's just people talking. I've come through much harder things than to worry about that."Modric seems to have found his feet with some sparkling displays, including a match winning performance against Chelsea on Saturday and the man himself has noted an improvement under Redknapp."I feel I've got better since Harry came to the club," he added."I'm getting used to the speed of football and the fact that I won't get a lot of time on the ball. You need to think quickly here."
