"A coach needs to be open for the future, but if I can choose, I prefer to be in the best leagues," Lopetegui, who has only coached in Spain and Portugal, told the BBC.
"England is a fantastic league. When you watch a match in England, you can feel the atmosphere, the respect for the players and the coaches. This is very important. I want to feel that.
"Of course, Spain is a fantastic league too, with fantastic players and coaches, but we will see."
Lopetegui was sacked by Real Madrid after a 5-1 thrashing by Barcelona at Camp Nou left the club in ninth place in La Liga, but the Spaniard does not hold any grudges against his former employers.
"I have all respect for the new coach (Santiago Solari), his new staff. And the players, I love them. They had a fantastic attitude with me," Lopetegui added.
"I would never say a bad word about Real Madrid. To manage the club is a fantastic experience for any coach. I hoped I could have more time but I have to look to the future."
Real are now second in the standings after 23 games, six points behind leaders Barcelona.
