The 21-year-old has made just three league starts for Madrid this season, coming off the bench on a further 10 occasions and netting three goals - including in Wednesday's 3-2 defeat to Sevilla.
Although Madrid were afforded plenty of the ball, they were not very effective and found themselves trailing 26 minutes in - Wissam Ben Yedder scoring his first LaLiga goal since February with aplomb.
A needless shove from Gabriel Mercado on Theo Hernandez then allowed Ramos to tuck away his second penalty, this time sending the goalkeeper the wrong way, but it came too late in the match for Los Blancos to nab a leveller. "Tomorrow we will be back to work, we have another game on Saturday [at home to Celta Vigo], and that's it".
Zidane refused to criticise defender Ramos for a performance which mixed defensive errors with grabbing the ball for both penalties his team were awarded. He was not ideal with the [missed] penalty, but that can happen.
Joaquin Caparros' side added the second a minute before half time with the easiest of finishes where Miguel Layun had an easy tap-in.
Real Madrid score two late goals but are still on the end of a 3-2 loss against Sevilla at the Ramon Sanchez Pizjuan.
"We were good in most areas, but we did nothing in the last 30 metres, nothing on the second line, nothing to worry the opponent", he said.
Real, whose only on-target attempt in the first half came from a Casemiro free kick up and over the wall, were struggling to really get going without a number of their star names in the squad. "But it was our own fault, we should have shown a bit more".
Cristiano Ronaldo, Isco and Dani Carvajal all missed out through injury, Gareth Bale was suspended and Toni Kroos, Luka Modric, Keylor Navas and Marcelo were rested. "Times have changed a lot since, but if it was up to me, I would have given the guard of honour to the team that has won the league".
Real Madrid dictated the early proceedings, controlling possession as they looked to play the game at their own tempo.
"But we can't be happy with the results we have in the league this season".
