BILBAO, Spain (Interstat) — AC Bilbao W will host Real Sociedad de Fútbol in a Copa del Rey round of 16 clash on Wednesday, a match that projects as a tight, defensive struggle.

The Interstat game simulator forecasts a narrow 1-0 victory for the visiting Real Sociedad de Fútbol. The matchup is the first of a two-legged tie, with the return fixture scheduled for March 4 in San Sebastián.

The home side enters with momentum from a cup run defined by offensive outbursts and one stark defeat. Bilbao advanced with a 4-3 extra-time victory at Cultural Leonesa on Jan. 13 and a 1-0 win at Ourense in December. However, it was routed 5-0 by Barcelona in league play on Jan. 7. Most recently, Bilbao earned a 2-1 league win at Valencia CF on Feb. 4, suggesting resilience after the Barcelona setback.

Real Sociedad de Fútbol’s form is a greater mystery, with its most recent competitive result listed from Jan. 1, 1970, indicating a potential data error or significant hiatus. This lack of recent performance history makes the simulator’s projection for an away win notable, implying strong underlying statistical metrics for the visitors not reflected in available results.

The winner of this two-legged aggregate series will advance to the Copa del Rey quarterfinals. For Bilbao, a positive result is critical ahead of a daunting league visit to Madrid on March 15.

Key Matchup: Bilbao’s attack, which has shown potency in cup play, against a Real Sociedad defense favored by simulations to produce a clean sheet. Bilbao’s ability to rebound from the 5-0 loss to Barcelona will be tested against an opponent with unclear recent form.

Projected Line (via Interstat): Real Sociedad de Fútbol 1, AC Bilbao W 0.

Kickoff: Wednesday, 9 p.m. local time at Bilbao’s home ground.
