Aston Villa manager Dean Smith complained of the five substitutes’ provisional rule after seeing his team lose to Liverpool.
Sadio Mane and Curtis Jones scored in the last 19 minutes while the Reds scored a hard-earned 2-0 victory at Anfield on Sunday.
Villa got the better of the game until the European, world and English champions presented Jordan Henderson, Gini Wijnaldum and Roberto Firmino shortly after the hour.
And Jones’ first Premier League goal of his career came just minutes after being introduced from the bench.
Teams are allowed to replace five players in a temporary change of rules for the rest of the season – introduced after the three-month suspension due to the outbreak of the coronavirus – which Smith believes favors teams with larger teams.

“I feel we won’t need to change the rules in one season,” said the boss of the Villa. “To get five submarines he always benefited the clubs with the largest and healthiest teams.
“I don’t really thank Jurgen (Klopp) for sending the big weapons! He made a triple substitution with three players who would normally start most games for Liverpool and improve their quality.
“We matched them for long periods but we didn’t show the quality in the third final.
“If we had played against any other team and we would have scored goals. But if you watch the rhythm of Van Dijk and Gomez and Alexander-Arnold, they are difficult to break down.
“The good thing is that we have beaten Liverpool here and not many teams will.”
Smith added: “I don’t want to be a brave loser. We had a gameplan for today, we knew that if we had come here and tried to beat the champions and the team that has scored an incredible number of points in the past two seasons, it would be crazy.
“We had a good structure and we knew we could be a good threat of counterattack. Unfortunately we have not shown the quality in the last third that they have shown for their goals
“I thought we would have limited the balls to the front three really well. We thought they had played a high line and the space was behind and we would have had opportunities.
“In the first half we had an opportunity from four to two and a possible cry of rigor in which Douglas Luiz is firmly convinced that he has been cut and fallen. We need some quality but also a little luck. “
