England's performances have impressed the United boss, who thinks that the current generation of Three Lions contains the perfect blend of ages and abilities.
"I think England must have a chance because the players are really good," Mourinho told Sky Sports. "There's a great generation of players at different ages and with different qualities.
"They have good experience at club level, playing in the Premier League and plenty of them play in the Champions League too.
"England have great potential to do something important."
"In South America, there are a couple of important teams," Mourinho continued. "In Europe the same three or four so I can't believe next summer we will have a huge surprise."
The draw for the World Cup takes place on Friday, December 1, with England seeded in Pot 2 for the tournament. Holders Germany, hosts Russia and European Championship holders Portugal are among the teams in Pot 1.
