I won my league last season (yay ^_^) but now my players all dropped a star and are at ± 97% now.

My strikers have like 140% shooting and finishing.. Is this still better than buying a new striker at 116% with but less shooting and finishing?
I don't really wanna sell him because he scored like 40 goals but then again, all his other stats are way weaker than the scout one

Many thanks in advance
