Sergio Ramos has accepted that he played poorly as Real Madrid were defeated 2-1 by Juventus in Tuesday's Champions League semi-final first leg.
The Spaniard, a defender by trade, continued his recent redeployment in central midfield as a result of the injury-induced absence of Luka Modric.
Ramos was slammed for constantly giving away possession in a "dreadful display" as goals from Alvaro Morata and Carlos Tevez either side of a Cristiano Ronaldo header gave the hosts the win they craved.
The makeshift midfielder admitted it was not a game he or the rest of his Madrid team-mates would look back upon fondly, but stressed the semi-final remains very much winnable for the reigning European champions.
"It was a bad game in general. I played poorly, but this does not worry me," Ramos told reporters after the game. "I trust coach Carlo Ancelotti and he trusts me.
"There is still a second leg to go and we can turn the tie in our favour. In this position - midfield - we run more, but I will not highlight any individual error of anyone.
"It won't be hard at all to play better at the Santiago Bernabeu next Wednesday than we did today. I'm sure everything will change. Giving up is not my nature, it's not philosophy and it's not in DNA."
Before clashing with Massimiliano Allegri's side in next Wednesday's decider in Madrid, Ancelotti's men will host Valencia in a difficult Liga clash as they look to keep pace or close the gap on leaders Barcelona with three games to go.
