Ferguson said: “Obviously we are disappointed but the good thing is we have big matches before the Benfica game to focus on.
“We can put Europe on the backburner and concentrate on Sunday’s match, which is massive for us.
“I am sure it is a game the players will relish given this result.
“We have five days to lift the team now. But if the players have ambitions to win the league they know how important Sunday is and I don’t think they will not let anyone down.”
