Can’t be more than Barça in any of those sports. Not football, not basketball, not women’s football, not futsal, not roller hockey etc.
The article that I posted and the list it contains is just the CL or the equivalent of the CL in all available sports in any given sports club in Europe. It shows that Sporting has 5 CL titles across all sports in total. Barça has by far the most in Europe with 45. The article is from early May and in June we won the handball CL for a record 11th time.
We also defeated you guys (Sporting) in the UEFA CL futsal final 4-0 last season to win our 4th futsal CL.
Only Inter Movistar has won more CL titles (5).
Obviously if all official domestic, European and international titles are included our football team alone has almost 100 official titles (domestic titles recognised by either RFEF, La Liga and official titles recognised by UEFA and FIFA).
Overall (all sports), I think it is approaching 500 official titles if that can do it.
Our many different and successful sports sections is one of the main reasons for the “més que un club” motto outside of the historical political element.
Anyway I enjoy our newly developed futsal rivalry, luckily Inter Movistar looks like a thing of the past and they are going downhill fast. They won’t be missed.
