Martyn Williams has backed the view of Wales coach Warren Gatland that there are too many foreign players turning out for Welsh regional sides.
The Welsh Rugby Union raised the number of non-Welsh qualified players allowed in each side from six to seven last season to counter the effect of World Cup absences, but Williams and Gatland believe there should be a reduction for the sake of homegrown players getting an opportunity to develop.
Blues flanker Williams told Rugby World: "By no means am I saying get rid of foreign players - they're brilliant players and most add to things - but for players who are potentially Welsh internationals to be sitting on the bench is not good for the national team, they need game-time.
"We have a small player base as it is, so to get stronger we need those players to be playing. You wouldn't see the Tri-Nations sides with two thirds of the squad not playing regular rugby. It would never happen."
