When developing your young players to become the future of you club, you take good care of them while they are in your walls. But one strategy of developing these players quicker is to send them on loan for first team experience elsewhere. Therefore you will want the same level of care given to your players when away from the club. It is a good idea to evaluate the side they are leaving for just as much as you would your own training schedules.
1. Will your player get into the first team?
Gaining first team experience has to be the most important aspect of loaning a player out. If the player isnít going to get regular time on the pitch then they will be better staying with you, with you controlling how much time the player gets in the first team. Consider where they are going to fit into the squad you send them out too. How good are the other players in comparison to your own? When sending your players out on loan for free you will want something in terms of value back, ie regular game time and a stats increase.
2. Send players to playable leagues
The way that Football Manager works when processing non playable leagues, or those not on full detail is to generate results based mainly on the reputation of the clubs involved to save processing power and keep DB size to a minimum. The lack of detail that the game processes in terms of match data will affect the development of the loanee, so the more detail that goes through each game the better it will be for developing your young players.
3. Training facilities
When sending a player out on loan you will want him to develop much quicker then he would if he stayed at home. Once a young player hits 18 or 19, he will be looking to gain first team experience and quickly accelerate his attributes to push for a first team place with you. The better the training facilities he uses, the more likely it is that his attributes will rise quicker. To send him to a club that has substantially poorer training facilities than you might be counter productive, and he may be better off staying with you.
4. Coaching Staff
You will want to trust that your young players are in expert hands when they are away from the club. Take a look at the coaching staff before you allow the player to leave, the coach calculator ( FM Coach Calculator ) can give you an idea of how many stars they will have in training. It is most important that they have a balanced team of coaches that will allow development in different areas for your young players. But if you spend alot of time developing your own coaching team, you donít want that time wasted with the young player experiencing substandard coaching elsewhere.
I think that it would be great if you were able to gain friendships and connections with other coaches, interact with them to ask the coach to concentrate on the development of certain areas when training your player. This may work as a real pull factor when you want to loan people yourself, making agreements to take good players on in order to use the expertise at your club, another way coaching could be improved.
5. Affiliation links
It is handy to consider all of the above when looking for feeder clubs for your side. Having a variety of feeder clubs to loan players out to could make it much easier to work in your own player development strategy, by sending players at different levels of ability to clubs in different leagues. If these clubs are able to offer balanced coaching with reasonable training facilities to develop a young player, whilst giving plenty of first team action to him it is much easier to handle your development strategy using affiliations.
Loaning players can be of considerable benefit to the clubs that get an extra player to bolster their squad. But loans should also have a benefit for you, to help squad management and development when looking for long term success.
