i haven't seen any clinical striker since FM 2008, so if you saw one please screen shot both description and attributes pages. or atleast tell me you've seen one. so that i can hope find one in the future and make him score 50 goals/season
well 1 striker can't do the job, ive never had a player score 50goals in one season for me, i think top has been 40 something. but was he clinical? not really it was more like my team scored loads in most matches and my strikers scored the extra goals in certain matches. even though they were quite so consistent, it wasnt like they scored every match(so quite so realistic in that feature). i feel that u need to have a good rotation system and maybe hope for around 2 strikers to be able to net 20+ each in max 35-40 apps if ur a top team.
but if u want someone who can score loads i think u need a Javier Hernandez type player, i would call him as being quite clinical in the game. u can find a few of those like Obinna and Delfoneuso(sp?).
but often a good team underneath them will help them achieve loads of goals per season.
