Hi mate, I would buy the acadamey, player as he will train faster and he will do well for your for 3/4 seasons, sell or keep the old boy for cover only, you can try and find one on auction if you wish but while your in the lower levels trying to get a young team is better, you .will find as you go up the levels that your acadamey players are well below skill than you would like so what most managers do is release the token player and sign the not so good free one just to sell and make some cash.
