Vedat Muriqi and Antonio Sánchez were on target as a late equaliser saw us settle for a point in a 2-2 draw at Rayo Vallecano.
Javier Aguirre continued with Abdon Prats and Muriqi as his forward line while Gio Gonzalez was introduced in the back four.
We could not have wished for a worse start as Alvaro Riveria gave the hosts the lead in the fourth minute when he was played through on goal and found the bottom corner from a difficult angle.
Chances were few and far between in a tightly- contested first half as Unai Lopez rattled the cross bar with a free-kick in the 39th minute.
We would go into the break level as Muriqi found himself unmarked in the box and fired home from the close range in the 44th minute, with the goal awarded after a VAR review.
We were the better side after the restart and got our reward 59th minute when Sergi Darder slipped Antonio Sánchez through on goal with a clever pass as our midfielder finished with expertise.
Dani Rodríguez would have out best opportunity to put the game beyond doubt in the 84th minute, but his strike from a tough angle was saved.
There was to be late drama as Raul de Tomas was handed a red card for a foul and reaction on Gonzalez, but it was withdrawn after a VAR review.
Gonzalez was adjudged to have handled in the box in injury time and Radamal Falcao made no mistake from the penalty spot to level the game, despite having had his first penalty saved and the referee ordering a retake.
