There are things in PES4 master league which frustrate me. Unlike in PES3, you aren't given the option of selecting if transfers are carried out or not. Personally I like other clubs to keep the same squads. The other thing is I think it would be better to start off in pre-season when beginning a new master league rather than going straight into first game of the season, it would allow you to carry out negotiations and have friendlies ready for the big kick-off
