There's very little to go on for this Copa del Rey match between Portugalete and Real Unión. We don't have recent results, scoring records, or past meetings between the two sides to look at, so there's no clear sign of which team is in better shape or whether this match is likely to be high-scoring or tight.

Because there's no form or history to compare, this looks like a genuinely even game with no obvious favourite. With so little information, the fairest reading is that it's too close to call and could well end level.
