Ryan Giggs has called on Manchester United to repeat their first-half show against Arsenal on Tuesday in order to complete their passage to the Champions League final. Such was the dominance of United's performance at Old Trafford last week, there is a slight feeling of disappointment at having not booked their place in Rome on May 27. Meanwhile, Arsenal will be hoping to take advantage of the fact they are still in the tie with a winning performance at the Emirates Stadium. However, Giggs feels the Red Devils are capable of repeating their dominance once more and feels that will be enough to end any Arsenal comeback dream. "If we play to the ability we did in the first half last week we will have no problems," said the former Wales skipper. "We went out to get the crowd going and play at a quick tempo. That is what we do when we are at our best. Arsenal are a top team and they are capable of scoring goals so we are under no illusions about how difficult this is going to be."
