Two things not previously mentioned:

1) Associations deadlock penalties bug. This has been happening since the year dot in one form or another and still hasn't been fixed (see the thread in the 'Bugs' forum).

2) Assistant Manager 'advice' in 2nd Leg of Cup and CL/SL knockout ties. He's reading the result of the 1st Leg the wrong way round and basing his 2nd Leg advice on that erroneous information (see the thread in 'Bugs' forum).
