The average game with the actual time the ball is in play is about 65 mins so to play with it in play for the full 90 mins would take about 2-3 hours and that is not going to happen.
It haid that Millwall were odds on to get beat and Lomas sacked from the start and even when they took the lead it was most obvious that we would score at least 1 goal so by wasting time they were seeking to gain an advantage.
