Quick tip: How to deal with time wasters

My opponent in this video was leading 4-3 by the 70th minute and decided to time-waste until the final whistle. Despite my best efforts to second man press and man mark, I just couldn't get the ball off him. I've found an unconventional tactic that sometimes helps regain possession: I force the keeper out while switching to my best defender, who I keep on the goal line. Typically, the opponent shoots from distance, allowing my defender to clear the ball back to one of my players and hopefully start an attack to score. I know it’s not the best method as it could lead to the opponent scoring again. However, given that there’s little in place to deter time wasting from keeping possession, it's worth a shot.
