'Ruud is one of the best finishers you will get,' said the Old Trafford chief. 'His speed of finishing is fantastic. He scored twice in the last game against Bayer Leverkusen - the key is to create the chances for him.'
'We have developed in Europe over the last three or four years,' he said. 'There is a great focus on the European games. It is a tremendous challenge - the biggest challenge.
'It is more tactical and other teams are more aware of your strengths and weaknesses. The best players in Europe are playing in the Champions League and players playing against the best want to be the best.
'Our players see it as a challenge and have reserved their best performances for it.'
