It depends on what is expected from their development, neither have played more than 5 senior games, so just to be involved with a senior squad and be in the battle for a place in the team is a big step up from playing age grade football. It will be up to the players to get into the team and stay there as the parent club and other clubs will be watching, if the loan isn't working then I am sure they could be recalled in the new year window.
Football is pretty simple, if you are the best player you normally play as winning a game makes everyone look like they know what they are doing, managers, coaches, boards and other players.
