Copa del rey espanyol plunges barca first defeat

I think there may be a small mistake there!

The correct phrase is "Copa del Rey: Barça suffers first defeat".

The Copa del Rey is the annual national cup competition in Spanish football, and Barcelona (Barça) is one of the most successful teams in the competition, having won it a record 30 times.

So, if Barça suffers its first defeat in the Copa del Rey, it means that they have lost a match in the competition for the first time in their history.
