The La Liga title race is coming down to a photo-finish between Barcelona and Real Madrid, with Atlético Madrid close behind.

Barcelona will face fierce rivals Real Madrid in a mouth-watering Copa del Rey final after they beat Atletico Madrid 1-0 at a feverish Metropolitano Stadium on Wednesday to complete a 5-4 aggregate win.

Barcelona could lose playmaker Dani Olmo and forward Pau Víctor for the rest of the season after the league said Wednesday that the club is not complying with financial fair play rules. Barcelona managed to register Olmo and Víctor after the government’s sports authority intervened with a provisional ruling against the Spanish league and Spanish federation’s decision to deny the club’s request because it missed the end-of-the year deadline to comply with financial rules.
