The victory came with a cost, as Arbeloa confirmed Ferland Mendy's injury after seeing the Frenchman go off at half-time, with Fran Garcia taking his place.
"It doesn't look good. We appreciate his effort; it's a risk to give him two games after so much time out, it wasn't the best thing to do," he added.
On a more positive note, he hailed the impact of academy graduate Thiago Pitarch. "We have to value the youth academy players, who didn't cost 30, 40, or 50 million, but they are lads who feel Real Madrid," Arbeloa stated with pride.
