Is it worth it buying top notch GK or not in your opinion?

[roguelover]

gk is something which is long term investment if u buy 18-19 year old and if u wanna build solid team u need good gk around 90 minimum and check his skills aswell imo u should check refelexes ,communication and concentration skills as they do make good difference in gamemy team gk lasts about 150-160 matches though but it goes higher for many teams depending upon age and if he is fast trainer or not and u dont need gk with special ability it hardly makes any huge difference
