Ghana midfielder Mubarak Wakaso much-anticipated debut in the Spanish top-flight for Alaves ended in disappointment as they were defeated 1-0 on Friday night against Leganes.
Wakaso, who joined the club at the start of the season, played the entire duration of the game and could not save his side from defeat.
Alaves, who lost the Copa del Rey final 3-1 to Barcelona last season before losing coach Mauricio Pellegrino to Southampton of the English Premier League, suffered a 1-0 defeat at Leganes.
With Argentine coach Luis Zubeldia now in the hot-seat but without midfielder Enzo Zidane, the son of Real boss and French legend Zinedine, missing from the match day squad, Alaves were unable to start their new era with a win.
In fact it was Brazilian striker Gabriel who scored the only goal of the game after 24 minutes for a Leganes side who narrowly avoided relegation last season.
The 23-year-old was alert to the opportunity which presented itself when Alaves goalkeeper Fernando Pacheco managed to only parry a deflected free-kick from Miguel Angel Guerrero into his path.
