Valencia lost back-to-back games for the first time in La Liga Week 17, while Celta Vigo claimed bragging rights in the Galician derby.
Valencia had the chance to leapfrog Atletico Madrid into second place and move six points clear of Real Madrid, but a bad-tempered Derby de la Comunitat against Villarreal saw Simone Zaza and Manu Trigueros both sent off in the final half-hour.
However, the winner was struck way before that as Carlos Bacca’s eighth goal of the season gave the Yellow Submarine a successive 1-0 victory.
A third derby rounded off not only the week but 2017 as Lucas Perez’s words came back to haunt him during Deportivo La Coruna’s 3-1 defeat to Celta.
Daniel Wass and Iago Aspas’ brace fired the visitors out of sight with almost the entire second half still to play, although Florian Andone pulled one back on the hour mark.
The result saw Depor fall into the relegation zone after Alaves beat Malaga two days earlier.
