Real Sociedad coach David Moyes says the Premier League boasts greater depth.
The former Manchester United and Everton manager told BBC Sport the bottom half of the table is stronger in England compared to Spain.
"The players in England are equally as good as those in Spain. Of course Real Madrid and Barcelona are incredibly good. Spain has the best two or three teams in Europe along with Bayern.
"But I would say the bottom half of the Spanish league is not as strong as the Premier League. I would come back and say sometimes we put ourselves down at home, knock the British managers, and I have seen there is little difference between them."
