BARCELONA, May 29 (Reuters) - Spain's highly rated teenage goalkeeper Iker Casillas insists he has virtually no chance of making his international debut in the European Championship Finals next month.

But such has been the remarkable rise of the 19-year-old Real Madrid stopper that no one in Spanish football would be surprised if he makes some kind of impact on the competition, hosted by Belgium and the Netherlands.

'Being in the starting line-up with Spain is not something that's even in my mind at the moment,' said Casillas, who this time last year was playing with Real Madrid C in the Fourth Division.

'I'm going to the competition with the idea of learning. To be around some of the best players in the world will be great for me.'

But those who have watched Casillas's meteoric rise from anonymity to international acclaim doubt whether he will be going to Euro 2000 just for the ride.

He has already proved himself to be a winner at international level, helping Spain to the European youth title and World Under 20 Championship in Nigeria last year.

He made his debut for the Spanish Under 21 side at the age of 17 while he was still at school and he has always shown confidence and composure beyond his years.

However, that early success has been eclipsed by the events of the current season with Real Madrid. Casillas received his call-up to Real's 25-man squad at the start of the season but was not expected even to figure on the bench.

Argentina's Albano Bizarri and German Bodo Illgner were ahead of him in the pecking order. He played a handful of games in the early part of the season under former coach John Toshack following an injury to Illgner and Bizarri's loss of form.

But it was not until Vicente del Bosque took over from Toshack back in November that Casillas was given a lengthy run in the side.

He responded brilliantly to the responsibility, keeping Real's Spanish League hopes alive with a string of fine performances and earning countless man-of-the-match accolades from the Madrid sports press.

He was also faultless in the Champions League. His performance at Old Trafford in Real's 3-2 victory over Manchester United was hailed as being worthy of his idol, the former United goalkeeper Peter Schmeichel.

He was impeccable again as Real beat Valencia in the Champions League final in Paris last week, making him a European champion just four days after his 19th birthday.

'It's true that things just couldn't have gone better,' he says. 'I wouldn't have believed it just a few months ago.'

In theory, Casillas is Spain's number three keeper, behind Valencia's Santiago Canizares and Jose Francisco Molina of Atletico. But Spain coach Jose Antonio Camacho has already hinted that Casillas may figure more prominently in his plans than has been suggested.

'Every one of the 22 players named has the same chance of playing,' Camacho insisted. 'When I call up a player I don't think abut his age. If he's ready to play for the national team I'll call him. Full stop.'
