Premier League pedigree and Champions League experience should make up for the Three Lions’ youthfulness, said the Manchester United boss, who has seen four of his Reds picked for the side.
"All of them play in the best domestic competition in the world, the Premiership, all of them playing for the best teams, all of them with experience of playing Champions League, which is a high level of football, obviously.
"They have good squads but good squads don’t always make good teams," he added.
Mourinho did not say explicitly if he thought England will go all the way, although he previously predicted Gareth Southgate’s men will make it out of the group stage.
However he predicted heartache for the national team soon after, with defeat by Brazil in the quarter finals.
After their humiliating 7-1 semi-final defeat to Germany in 2014, the South Americans will be hoping to recover their pride.
