Liverpool manager Jurgen Klopp believes the Premier League is the toughest European league to achieve success in.
Spanish teams have dominated European football in recent years winning the last three Champions League and Europa League titles.
Klopp, who has just begun his first full season in charge at Liverpool, puts this down to the amount of competitive teams in England and the volume of games. And he also highlighted the games played over the Christmas period -- not saying that there should not be games, more the number of them.
He told the Daily Mail: "Play on December 24, play on December 26, I love my family but for me I prefer to play football. But then we play December 28 and 31, and January 2 and I am thinking: 'OK, now we need three teams for this.'"
He added: "The biggest difference between England and the others is that the competition is always so hard. So, yes, you can play three games if you have teams with special ability, like Manchester City or Manchester United -- two teams and let them play.
"The big difference to Spain is that Barcelona can play 50 percent of their games with Team B; or there are games where Lionel Messi runs 4.3 kilometres but scores five goals. That's a recovery session. England has no recovery session, in absolutely any game.
"You can win, you can win high if you break them at a specific point, but until that point it is always hard, hard, hard. So you get three games, 26th, 28th, 31st, at the highest intensity. Not one second of recovery."
