It will improve the quality of the national team  Reducing the number of foreign players would be good for the national team. Current rules mean that only a few domestic players get a chance to compete at the highest level, and the national side suffers as a result. So while, for example, English clubs with the ability and clout to sign foreign players have done very well in the Champions League recently, the English national team has performed badly. English youth are consistently overlooked for places in the best sides in favour of more talented, more experienced foreigners who offer short-term success. Limiting the number of foreigners would force clubs to give more local players a chance to develop, and subsequently improve the quality of the national side.
