I want to know the answer to the following question:
On what date did the FC Barca hold a second testimonial match for Paulino Alcántara against the Spanish national team?
All the background I'm provided with is that "This coincided with the transition to professional football, and, in 1926, the directors of Barcelona publicly claimed, for the first time, to operate a professional football club.". Is that enough to answer the question?
Answer: no
