Speaking after the Champions League Draw, Begiristain also found time to praise his manager:
Meanwhile, Begiristain has issued Celtic with a firm warning after the two clubs were drawn together in the last 16 of the Champions League.
"We will go to Glasgow to win," he confidently declared and underlined the importance of the first leg at Celtic Park, where Celtic have suffered just one defeat in 16 Champions League games.
"We must be ready and very focused. The first leg is massively important."
