Match preparation greyed out

[Gwynbach]

Hi there,

 

I am playing St. Albans City in the National League and I'm finding that my players' attributes are decreasing and the coach assessments are worse - for example, a 28-year old left back signed as a decent NL player is now a leading star of the league below, despite having no injuries.  I can understand this with older players and those who suffer bad injuries but this applies to a lot of my players.

I would like to change the match preparation time to minimum but unfortunately the slider is greyed out.  I've made sure that it's me and not my assistant who has charge of match preparation training but I still can't change the slider.  Any ideas?

 

Thanks,

 

Gwyn
