Rangers' best chance of stunning PSV Eindhoven is targeting their calamity keeper Walter Benitez, according to former PSV Eindhoven boss Aad de Mos.
Michael Beale's side travel to the Netherlands this week for their crucial second leg Champions League play-off after a 2-2 draw at Ibrox last week.
Argentinian keeper Benitez was criticised in the Dutch media for his performance and distribution in Glasgow and also was partly to blame last year for Antonio Colak's winner after his pass to defender Ramalho was intercepted by current PSV loan star Malik Tillman who set up the Croatian, who now plays for Parma.
And de Mos - who also managed Ajax, Anderlecht, Standard Liege and the United Arab Emirates - is worried about the former Nice goalkeeper.
He said: "I think Rangers only have a chance if Walter Benitez makes another error.
"He makes a mistake every week.
"He was to blame for Ramalho conceding that goal against Rangers last year, he was to blame for putting Jerdy Schouten in trouble against Vitesse Arnhem last week.
"And he was to blame for Ibrahim Sangare losing that ball in Glasgow. He shouldn't pass it out like that, he should just get rid of it.
"Peter Bosz should do something about it. There is confusion between him and the two central defenders."
