I saw that Luis Diaz played for Liverpool last night even though he had previously played for Porto in the Champions League, which is now allowed under UEFA rules.

Got me wondering what purpose the cup-tied rule now serves in domestic football. Any advantage it was trying to eliminate is significantly reduced by transfer window restrictions. Also the general lowering of importance of cup competitions for the biggest clubs vs say, finishing 4th or above in the Premier League.

Maybe it has outlived its usefulness and should be abolished domestically.
