European Commission President Jose Manuel Barroso called on Thursday on leaders to display compromise ahead of a key European Union summit to address the eurozone debt crisis. As France and Germany struggled to reach common ground on ways of stemming contagion from the crisis, Barroso said there would be \"a positive\" result if all maintained \"a sense of compromise.\" Speaking at a Brussels conference, Barroso said it was vital to reach agreement on strengthening Europe\'s rescue fund, the European Financial Stability Facility (EFSF), its primary weapon to stem the crisis. \"If there is one aspect to outreach all the others it\'s the need to reinforce the firewall,\" he said. Eurozone finance ministers gather in Brussels from Friday with EU leaders due in for a summit meeting on Sunday. He added that a \"very positive outcome was possible on Sunday if there is a sense of compromise by the participants.\" \"Europe needs a sense of compromise,\" he added. \"I\'m confident you\'ll do it.\"
