Douglas Ross says he has "serious reservations" about the creation of a European Super League amongst the biggest teams in the continent.
The Scottish Conservative leader and part-time assistant referee said fans of the English clubs who signed up, Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham, would be left with a poorer product.
Speaking on BBC Breakfast Ross was asked for his view on the news about the league which emerged late last night.
In a move for European football, the Premier League clubs would join AC Milan, Atletico Madrid, Barcelona, Inter Milan, Juventus and Real Madrid to create a new midweek competition.
It's believed, under the plans, that clubs would still compete in their national competitions.
The move has been slammed by a number of politicians, including the Prime Minister Boris Johnson and Labour leader Keir Starmer, following the announcement.
Douglas Ross said: "I think there have been many concerns raised by the government, by UEFA and others. I think there are serious reservations about what's been proposed.
"It would have a massive affect for football and there is a real danger that fans of the Premier League, which is one of the most success leagues anywhere in the world, would be left with a lot poorer product at the end of this.
"I understand why certain clubs are appealing for this, but overall it would be a deeply regrettable move."
Boris Johnson posted his views on Twitter on Sunday evening, criticising the prospect of six English clubs possibly joining a breakaway continental league.
"Plans for a European Super League would be very damaging for football and we support football authorities in taking action," said Mr Johnson.
"They would strike at the heart of the domestic game, and will concern fans across the country.
"The clubs involved must answer to their fans and the wider footballing community before taking any further steps."
