choices
depends how you want to do it. you could select players from the unattached players section but they are mainly 'resurrected' players who have recently retired.
here is a selection of players who will do a good job for you in the league and also improve statistically as they are young.
goalkeeper - there is a dutch keeper called jacobs who comes along at some point during master league and he is much better than the stats show.
right back - chiqui arce
defensive mid - muntari from udinese, he is a top notch all round midfielder. like davids but with room to improve.
offensive midfielder - Yapi-Yapo, a good player who has brilliant ball control and i find him best used on the left wing. also has a decent shot and is a good finisher
playmaker- alexi aguinala (aguinaga really). altho he has poor stamina he is technically brilliant. he is 23 on my league but already has 97 technique
striker - Bojinov from fiorentina. a young bulgarian player who has great power on the ball and good skill. only thing he lacks is real pace but he troubles most defences and has a good header
