Barcelona coach Luis Enrique is happy seeing Eusebio Sacristan in charge of Real Sociedad.
The former Barca B coach took charge of La Real after David Moyes' sacking.
"Even though we have only one game as a reference for the new stage of Eusebio's career, it has helped us to see what he wants from his team - the kind of pressure situations they did not have before, and it worked," said Enrique.
"We know the taste of Eusebio. He is a rival to be reckoned with. La Real have quality players that can hurt you with the ball.
"And with Eusebio, a plan will be carried out. It will be difficult for sure."
