Just looking at the countries involved, you'd think this will be a one-sided thrashing. However, Finland were able to steal a 1-1 draw in Gijon in the first meeting between these two. There won't be any fear from the Finns in this match.
Those dropped points could prove critical for Spain. They're only one point ahead of France for first in Group I. Both Spain and France will want to avoid that second spot and having to qualify for the World Cup through the dreaded playoff.
Finland still have a mathematical chance of finishing in the top two of Group I, but the chance of them doing so is minute. They are four points behind France and will have to get a result against Spain to try to keep pace.
Without any further ado, here are tonight's lineups...
Yet, despite Spain's slip-up in Gijon, they have been very consistent on their travels and have won all three of their away matches in Group I, scoring six goals without reply.
Can Finland cause another upset and allow France to replace Spain at the top of group I? Bringing you all the action from the Helsinki Olympic Stadium, my name is Max Bentley.
In fact, Mixu Paatelainen's side have drawn their last two matches against La Furia Roja. The 1-1 draw in Gijon back in March marked the first time that Spain had dropped points in an international tournament qualifying campaign since Iceland's 1-1 draw in September 2007.
Victory for Spain tonight would edge the world champions closer to cementing their place in the 2014 World Cup finals in Rio de Janeiro but they face a Finland side which has proved difficult to crack in recent years
