Fabian Canobbio's strike was enough to hand Schuster's side their second league defeat this term, leaving them fourth of the table.

However, Schuster remained cool once again, despite a poor run of results during the past couple of weeks.

"We had no luck. Except for the goal our opponents did not create problems for us," the German told a news conference.

"I am calm. We are working and doing what we have to do."

Spanish reports from last week suggested that the Valladolid game could be crucial to Schuster's future at the club, following an embarrassing cup exit.

The Spanish giants' were eliminated from Copa del Rey at the hands of third division Real Union, who hit six goals on aggregate past the Real defense.
