Liverpool coach Rafa Benitez believes it is 'amazing' to get Premiership rivals Chelsea in the Champions League semi-finals for the third time in three years. The Reds face another all-English contest, following their breathtaking 4-2 defeat of Arsenal on Tuesday, which saw them go through 5-3 on aggregate. "It is amazing that it is Chelsea again, and just as before it will be a very, very tough game," said the Spaniard. "Will that be an advantage to Chelsea? I don't know, these games are always very close. I will tell you after the matches who had the advantage." Benitez was responsible for ousting the Blues in 2005 and 2007, eliminating Jose Mourinho's side on both occasions. The former Valencia tactician was happy with his side's performance, particularly in the second half, when they scored three times to deny the Gunners. "I was delighted with the belief of my players, particularly in the second half. We had been so poor before the break, but so much better in the second period," he said. "It was a tremendous game for our fans, there were six goals and we played so well. "Now we have Chelsea again in the semi-final. Again it will be a very, very tough game against an excellent side. But we have enough experience of such matches and clearly the belief to succeed again." The first leg will be played at Anfield on April 22nd, while Chelsea will host the second leg a week later.
