In what way?
If it comes up with something like an age cap or putting a limit on the number of players that can be loaned out by a club each year then the clubs will be more careful as to how many they should buy and for what price.
1. Limit on players being loaned-out
Example Chelsea:
They have over 26 players on loan, 8 of them are in Vittesse Arnhem alone (Many were bought from them and loaned back to them for their 'development') and they have no intention upon bringing them back to their team any time soon, which would of course help those teams who have those players on loan, like Everton or Atletico Madrid but what when the time comes, then the clubs like Vittesse will surely be effected. They are selling because offers are coming that are hard to reject with the money involved, but if they imposed these sanctions then the offers will be reduced.
2. Age cap
Example Man City:
Consider Barry, Adebayor, Santa Cruz, Jo, etc. They all are/were being loaned out because the clubs no longer need them and their wages are too high. If there was an age cap for the players being loaned out then clubs would think twice before buying players involving huge contracts.
Things like these would definitely help small clubs who are looking to protect their players, although the players would want to go to a bigger club but knowing that there are risks involved with that money they would weigh their options carefully and not go running to sign the contract and end up being on the bench/back to the club they came from/In search of another club willing to take them on loan etc.,.
If sanctions like these or similar to these were at place long back then Southampton won't be fretting about losing their priced possessions at the end of the season despite moving in the right direction.
P.S: The examples above were given just to illustrate the problems but not used in anyway to criticize those clubs' models because almost all clubs are looking to exploit the loop holes of the loan system which is only natural but clubs with a lot of money are always in the spot-light and so the examples were used for a better understanding.
