Nigeria coach Stephen Keshi says that "anything can happen" ahead of their crunch Confederations Cup clash against world and European champions Spain.

The Super Eagles come into the game needing a win to keep their slim hopes of progress alive - though Uruguay are expected to bag a big win over Tahiti.

Nigeria whipped the minnows 6-1 in their opening encounter but a narrow 2-1 loss to Uruguay was enough to hand a severe dent to their ambitions at the tournament.

Despite the odds being heavily stacked against the 2013 Africa Cup of Nations winners, Keshi says that they are excited ahead of the match.

"We can't wait to play them," he said. "Anything can happen. That's what makes this such a great game.

"It doesn't matter who we are playing, as long as the boys do what we want them to do. We will just play our game.

"Against Uruguay they did everything we asked them to do. We had more possession, we had more shots on goal... but we just didn't take our chances."
