Manchester United fullback Diogo Dalot says "belief" will be key against Champions League opponents Barcelona tonight.

United need to overturn a 1-0 deficit to reach the semifinals.

“I think it (belief) will be 90 per cent of the game. As long as we keep belief in ourselves in the game, I think we should do the rest, play the game and be ready for 90 minutes and injury time. We then just need to focus on ourselves and believe until the end," Dalot told manutd.com.

“Yes, of course [we believe in ourselves]. We've proved to everyone that no one at this club gives up and we still have the Paris night in our minds. We need to keep that in our minds just in terms of belief and fighting for the result. It's different games and different teams but we need to keep that in mind to motivate and to be ready.“
