Pro Evolution Soccer 2016

The easiest way to get this is by first heading into edit mode, any team in the Champions League will do but I chose Real Madrid. Edit all of the players in the team to 99 for every stat then head on into the Master League as manager of Real Madrid.
Once you have started the Master League go on ahead and skip every match, the edited team should win every game with ease but make sure to save before knockout matches in the Champions league and Domestic cup just in case.
In around 30 minutes you should obtain the following achievements if you haven't got them already;
European Treble Winners
Kings Of Europe
Champion Manager
After the season has finished, wait a few more weeks and you should also unlock;
No.1 Club

Hope this helps you mop up these annoying achievements quicker! :)
