Forlan was disappointed that they conceded two away goals in the first leg of their Champions League tie with the Portuguese giants.
“We know that it is not the best result to take into the away leg, but there we are,” he told Canal Plus.
“Now we have to refocus on the league and then when the second leg comes around we can start to plan how to obtain a good result there.”
“We knew that they are quick up front and there was a mistake and they took advantage and they scored a vital away goal. They played well,” he continued.
“Now we have to remain calm, try not to make any more mistakes and to create chances. We also have to be defensively solid.”
