Qualification Not Achieved Yet - Zidane

French star Zinedine Zidane has a cautious attitude towards Tuesday's crucial Champions League quarterfinal match in Monaco.

"I don't think qualification is achieved yet. This is a big game and we are not in the semi-finals yet," he said.

"We played well in our last match at Albacete and we are in our best form for two or three weeks," he added

Zidane also notes the importance of a good start as one of the keys to victory on Tuesday.

"We must score first, if Monaco score first then it will be a different game. We will be playing against a good team in a strange atmosphere," said Zidane.

"We can't come here expecting to win, we must be at 100%. If we go onto the pitch in the wrong frame of mind we could be in for a nasty surprise. This is the quarter-finals of the Champions League," he said.
