should i flog my top rated player due to consistent bad ratings?

[Vicez]

Hi i have 1 7 star in my team he was a scout and he is a mc ive brought 2 mc scouts one last season that guy played badly for most of last season but has recently picked up great form. The 7star has been mainly getting 5s a few 4s a few 6s his av is 5.3

Not sure whether to keep him and hope or flog him but i have had alot of players who start off bad then become key players ive never had luck with mcs.

Last 5 games have been 5,4,6,5,5 hes scored 5 goals and 1assist in 21games.
