Arbeloa has been in charge at Real since January 12, with the club going on to lose to second-tier Albacete in the Copa del Rey and Benfica in the Champions League. They have also beaten Levante, Villarreal and Rayo Vallecano in La Liga, as well as Monaco in Europe's elite club competition.
Speaking after the defeat to Benfica, he said: "I do not regret any message I delivered because it reflects what I believe in. If your conclusion is that today's match was like this because the front players did not run enough, I completely disagree with you."
He added: "Clearly, today we were far from where we wanted to be, far from the difficulty of the match, from the opponent's requirements, from the atmosphere, and from what they were playing for, and what we were playing for. I think we weren't able to rise to the level we needed throughout the 90 minutes."
He added: "Before we came here, we knew we had a lot of work ahead of us, a lot to improve, and we are fully aware that there is still a lot to be done. To win this type of match, you have to do many things right, not just one thing, and you have to do them for the full 90 minutes."
