Croatia coach Robert Prosinecki feels Galatasaray can defeat Champions League opponents Manchester United tonight.
Prosinecki feels the home support can be a decisive factor.
He told Fanatik: "The biggest power is of course the fans, but in such matches, on-field power similar to the performance of the fans is required.
"There is no need to say much about Galatasaray's offensive line. It is enough for Icardi to have the right support, to bring the ball to Icardi and for Icardi to have the chance to score.
"However, their defensive organization is important for opponents of this quality and the absence of Davinson Sanchez is undoubtedly the point that worries Okan Buruk the most.
"Galatasaray is closer to winning the match if it does not have any problems in defence."
