Former Manchester United midfielder Bastian Schweinsteiger is impressed by the football IQ of Bruno Fernandes.
Fernandes will be back with United shortly after Portugal's World Cup defeat to Morocco on Saturday.
Ahead of his return, Schweinsteiger has praised the midfielder's football intellect.
The former German midfielder said: "I call him 'the brain'.
"Like he literally moves so smart on the field and do you know what, you actually like kind of underestimate [his work rate].
"Of course, he's making his assists, or he is scoring the goals and makes great passes but Bruno Fernandes, he is working very hard."
