RUBEN AMORIM is not taking progress to the Europa League final for granted as he admitted Manchester United have a tendency to “lose our mind a little bit” when the going gets tough.

The United boss believes his side need to score in Thursday night’s semi-final second leg against Athletic Bilbao despite boasting an authoritative 3-0 lead.

The Red Devils enjoyed one of their greatest ever European away days last week as Casemiro’s header was complemented by a Bruno Fernandes brace after Dani Vivian’s red card at a stunned San Mames.
