Sergi Barjuan has insisted that Barcelona must learn from their defeat at the San Siro ahead of their quarter-final first leg clash against Paris Saint-Germain this evening.
The former Barcelona and Spain international defender has urged the Catalans not to take any unnecessary risks ahead of the first leg tie with PSG to ensure they reach the semi-finals for the sixth time in six years.
Barjaun stressed that Barca cannot afford to make the same mistakes they made against AC Milan, when they were beaten 2-0 away to AC Milan in the first leg of their round of 16 tie.
This left the Catalans with it all to do, and although they did turn things around in the return leg at the Nou Camp, Sergi has insisted they will have to be more cautious when they face PSG.
"The Milan game is a lesson on what not to do. It's not a final being played in Paris. The team has to come back with the guarantee of going through, there will be another match at Camp Nou," the former defender told Marca.
"The most important thing is to score at the away ground, come back with a goal in the bag, more than a win. That would make things difficult for PSG, although we had the experience of what happened in the Copa del Rey with Real Madrid [Barca lost 3-1 at home].
"It will be very interesting because both teams have a huge amount of potential, with regard to attacking. PSG demonstrated that at the Mestalla stadium in the last 16 round, although then, in Paris, they tried to make the result secure."
PSG progressed to the quarter-final after beating Valencia 3-2 on aggregate, and had the advantage of only needing a draw in the second leg.
However, they will be at home for the first leg this time and so will be looking to shut up shop at the Parc des Princes and head to Catalonia with the lead. Not conceeding an away goal would be a binus for Carlo Ancelotti's side.
