Barcelona’s hot scoring form of late has Luis Enrique confident that his side can not only knock out Paris Saint-Germain from the Champions League  tonight, that they can do so with goals to spare. Recent routs over Celta Vigo and Sporting Gijon have boosted the Catalans’ morale and their optimism is high going into the return leg of the last-16 tie,  despite their 4-0 deficit. Messi and other Barca players “We are in the middle of the tie, we have nothing to lose and a lot to win – if they scored four, we can score six,” the Asturian told the press yesterday. “We arrive in good form and we have to be confident. Without a doubt, we have to be patient as the result of the first leg was very clear, but we are only halfway through. “We have to do a lot of things throughout the game and assert our dominance in attack and defence because PSG are a difficult team and will make things hard for us. “Everyone has to be professional and know that sport puts you in situations of all kinds. If this team has not needed a comeback like this so far, it’s because we’ve been generally very good in our first legs.”
