Sir Alex Ferguson says his Manchester United stars will recover quickly from their Champions League defeat by Celtic, especially with a crunch showdown with Chelsea on the horizon.
The Red Devils lost 1-0 at Parkhead on Tuesday evening to leave their European hopes in the balance, but Ferguson is already looking ahead to Sunday's meeting of the Premiership's top two.
He 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.
"It was a shock to lose, really hard to take. We threw this game away because we did not take our chances.
"To qualify we need a point off Benfica. It is a home match, so we will try to win.
"I have no worries about our home form, or our character. But we need to get that result."
