Simply start up a new Career mode as a Manager, skip to the first game (whether it is a league game or from the Invitational Cup). Choose to Sim the game and let it run till around the 75th minute, or later (that is when I jumped in) and hop in (my team was up so the current result does not matter), I chose to score more goals, ensuring the win and upon completion you will be rewarded with your achievement.

Hope this helps.
