Messi & Iniesta milestone, Roma's impregnable fortress: 5 vital stats ahead of kick-off
• Only two teams in Champions League history have overturned a three-plus goal deficit from the first leg in the knockout stages – Deportivo vs Milan in 2003-04 and Barcelona vs PSG last season.
• Roma have never lost at home vs Barcelona (W1 D1). That one win was a 3-0 victory in February 2002, a result that will see them through here.
• Barcelona have conceded just three goals in this season’s Champions League, fewer than any other side. Fortress.
• Roma have not conceded ANY goals in home Champions League fixtures this season.
• Andres Iniesta and Leo Messi have become the first players in HISTORY to reach 100 Champions League appearances together.
