Ruud Gullit has cautioned PSV and Feyenoord ahead of their Champions League matches against Viking FK. The Norwegian club appears to be the weakest opponent for the Dutch teams, but Gullit is on his guard.
Gullit believes that the key to success is not to give away too many chances and not to concede goals when it doesn't work. He points out that it's not in the nature of Dutch teams to give away goals, as foreigners know that they want to play football and will try to take the ball.
The clubs can go into the duels with confidence, but Gullit sees a similarity with Bodø/Glimt, who defeated NEC. "It must be possible, you just have to believe in it," he said on Ziggo Sport.
