K-1 is returning on May 27 in Madrid, Spain at the Palacio Vistalegre so it was expected to have some Spanish fighters on the card. The event is supposed to be a K-1 MAX event and possibly the Final 16 for this year's K-1 MAX.
Abraham Roqueni will be representing Spain on the card and he'll be in the K-1 MAX selection. Nothing has been confirmed by K-1 about the card being the MAX Final 16 but Roqueni's people have said that it is and that he's in it. Roqueni would be the first fighter from Spain to ever make it to the K-1 Final 16.
It doesn't come as a surprise that Roqueni is participating. Simon Rutz of It's Showtime seems to be working very closely with the new K-1 and Roqueni has fought for him before in June of last year. He's also scheduled to fight for It's Showtime in July. Roqueni also isn't managed by It's Showtime so the notion that K-1 would just be all It's Showtime-managed guys is proven a bit wrong, even though there is an obvious connection between Roqueni and Simon Rutz, having fought for It's Showtime before.
Roqueni will be a bit busy a month before K-1 kicks off though. He's fighting Albert Kraus on April 14 in Torrelavega, Spain so he's got his work cut out for him. Others that seem inevitable for K-1 MAX this year are Andy Souwer and Albert Kraus.
