It was an easy match to officiate. Not many fouls were committed.
Still Mallenco missed a couple of fouls: an elbow by Denneboom, ankle attacks and a couple of wrong throw-ins and off-sides, but no major mistakes. All bookings seemed also correct to me.
Twente was better in the first half. Halfway they must have realized they could win. This scary thought made Twente collapse in the second half. Arsenal played on routine. The first goal came after a free kick, not correctly given after an assistant waived Mallenco for a foul. After this first goal the game was over, as well as Twente's adventure in the Champions League. Maybe they'll get another chance in the next century.
The same assistant was wrong with two off-sides, as well with two throw-inns.
