It is possible to train outfield players to play in a new position, if you think his skills are better suited for a different role, this is a good option but costs a fee.
It is also possible to add new playing side to a player, for example a center midfielder (MC) can train left or right sides, making him MCR or MCL or MCRL, this also costs a fee.
