I suggest you keep him but also have another back up striker. i have 2 striker, both 7 stars (51 quality right now), 24 year old one was my main one, but slow trainer got him from the beginning of this season. he play fair. 1 goal in 2 match average. my another one is 21 year old, got him in the 3 week of the season, fast trainer. but not playing really go. both have one-on-one skills, my major game, i will give to my 24 year old, minor game, i will give 21 year old a chance (yea, and i lose my last game vs a 36 quality team, while my first 11 were 47.4). but i think striker is not a big deal at all as long as you have wings or AMC cause they score more~
