Milan striker Hernan Crespo who scored in Milan’s 1-0 win over Manchester United at Old Trafford, says the Champions League tie is far from over.
“We shouldn’t think that we are already through,” said the Argentinian striker.
“It was an important goal but it hasn’t decided anything yet, the win was just a good first step.
“In games like these it can be fatal if you stop concentrating,” added the striker, who is on a season loan from English club Chelsea.
“They have shown that on many occasions against many different teams. They are a team that always battles and that is why we have to be on our guard right until the last minute at the San Siro.
“Sure, we got a great result which is to the credit of the whole team who showed we can play good football but also we can cope when things aren’t going for us.”
Milan coach Carlo Ancelotti suggested that United’s pace on the break would their main threat for the return in Milan in a fortnight’s time.
“It will be a very difficult game in Milan. Their pace is formidable. Manchester are a strong team with determination and speed,” Ancelotti added.
“I was very happy with our performance — we were able to play our game and keep possession and I was particularly pleased with the way we were able to break up their rhythm.
“But we were also lucky. On a couple of occasions in the first half their pace had us in trouble and they could have taken the lead which would have made it an entirely different game.
“This was a historic result for us but what matters is getting through to the next round”.
