"The Parker Pen Challenge Cup is a very important competition to us," said NEC Harlequins Chief Executive Mark Evans. "We do not know much about our Spanish opposition, but their domestic record is very good. We are sure that it will be a difficult tie, particularly the leg in Valladolid. There are some very good teams in the competition and as one of our objectives is to qualify for next season's Heineken Cup, success in the Parker Pen Challenge Cup is vitally important to us. This competition has also given a number of players who have performed well for us in the Zurich Premiership and in our 2nd XV, the opportunity to stake a claim for a regular spot in the starting XV."
