Spain coach Vicente Del Bosque expects Finland to be more adventurous in attack than they were in March's 1-1 draw in Gijon when the teams meet again in Friday's World Cup qualifier at Helsinki's Olympiastadion.
Despite dominating the game earlier this year, Del Bosque's world and European champions conceded a late equaliser on the counter-attack - one of the few times the visitors had ventured forward.
Spain top Group I, holding a one-point lead over nearest rivals France, with the Finns five points adrift of Del Bosque's side in third.
``I don't think we will be able to dominate the game like we did in Gijon. A win would put them a lot closer to the top spots,'' the Spain coach said in a press conference, quoted in AS.
``They defend well in numbers and get men behind the ball. But their transitions are quick and they are dangerous. A dead-ball situation could do us damage.''
A win on Friday would guarantee Spain a place in the play-offs, but Del Bosque said it was imperative they took maximum points, stressing that none of their three remaining opponents - Belarus and Georgia in addition to Finland - would be easy.
``We have to win all three games,'' he said. ``We know from experience that there are no easy rivals. We had difficulties against Finland, and in beating Georgia. We can't think that they're three easy games. Now any team that is organised like Finland are can cause you problems.''
Spain are without midfielder Sergio Busquets, who had to withdraw from the squad after picking up a thigh injury in Barcelona's 3-2 win at Valencia.
Del Bosque admitted the absence of Busquets, adding to the injured Xabi Alonso, means his midfield will have a different look, but expressed confidence in their replacements, such as Atletico Madrid midfielders Koke and Mario Suarez, and Manchester City's Javi Garcia.
``The core of our national side is based on Busquets and Xabi Alonso, who aren't here. But in Spain we have a lot of midfielders in this position and I'm sure that one of them will solve that problem,'' he said.
``We shouldn't over-dramatise these withdrawals, because we have people behind them who can do very well.''
Another question mark is in goal. Del Bosque has long been loyal to captain Iker Casillas, making him the number one choice in the Confederations Cup, but the fact the Real Madrid stopper has not played a single league game this season has led commentators to believe Barcelona's Victor Valdes will start against Finland, after the Catalan featured in a training match alongside Del Bosque's likely starters.
``We'll announce the decision on Friday,'' Del Bosque added.
``We have doubts in other positions but in goal we already know. We have three extraordinary keepers (Napoli's Jose Reina is the third), and any of them could play perfectly well. I have personal sympathies with each of the three and I believe in them as footballers.''
Finland coach Mixu Paatelainen acknowledged at his pre-match press conference that, despite their absentees, Spain would be formidable opposition.
He said: ``We're a modest team and play against the best team in the world. Brazil beat Spain in the Confederations Cup final, but I still think Spain has the best squad in the world.
``All of their players are first class.
``Whichever player does not play, the team is not weakened. Players who are not even in their squad this time would be key players in our squad.''
