PARIS, May 25 (Reuters) - Real Madrid's emphatic 3-0 defeat of Valencia in an entertaining Champions League final gave one former Real player in particular cause for celebration.

The manner of Real's victory and the performance of several key players will have had Spain coach Jose Antonio Camacho purring as he prepares for next month's Euro 2000.

Fernando Morientes and Raul Gonzalez, who scored Real's first and third goals, are likely to form the first choice partnership in attack in Spain's opening group matches against Slovenia, Norway and Yugoslavia.

They will be joined in the squad by defenders Michel Salgado and Ivan Helguera, who were both outstanding against Valencia, and captain Fernando Hierro, if the experienced centre-back can make a full recovery from a knee injury that limited his appearance in the final to a few minutes at the end.

Real's gifted young goalkeeper Iker Casillas could also win a last-minute promotion from the under-21 squad after his superb performances in the latter half of this season.

Casillas, who turned 19 a few days before the final, may well have to watch his opposite number at Valencia, Santiago Canizares, keep goal for the national team.

The performance of Canizares in Wednesday's final will have satisfied Camacho, despite the scoreline.

The former Real keeper made two outstanding saves in the first half to keep out a Nicolas Anelka header and Steve McManaman's first attempt at a volley from the edge of the area.

Canizares was let down by his defenders on the first goal, could do little about McManaman's second and was left completely stranded on the third, as Raul was allowed to run clear on goal for 60 metres without a challenge from a Valencia player.

The one disappointing note for Camacho will have been the performance of Valencia midfielder Gaizka Mendieta, who struggled all night to impose himself on the game.

Mendieta has been pencilled in by Camacho as the side's right-sided midfielder, to play in place of the injured Luis Enrique Martinez.

Much was expected of him in the final but the Valencia skipper found himself out of his depth in a midfield battle that Real dominated.

The one consolation for both Mendieta and Camacho is that Spain are unlikely to come up against a midfielder of the calibre of Fernando Redondo during Euro 2000.

Vicente del Bosque's Real side played with a genuine swagger, from Casillas in goal and Helguera in the centre of defence, through to McManaman, Redondo and Raul in midfield and Anelka and Morientes up front.

That class in the end proved too much for the less experienced men of Valencia and Real were able to clinch their eighth European Cup win and second in three years.

The task now for Camacho is to instil the self-belief so manifest at Real in the national team, which has a record as meagre in major tournaments as the club side's is impressive.
