Ahead of today's trip to Chelsea, Carrick admits he's appreciated the Brazilian's influence since taking charge in January.
"He's certainly got the knack and the feeling, and that sense in and around the box," he told MUTV.
"He's got that sixth sense, in some ways that you can't necessarily coach or you can't necessarily always give the perfect moment or the action or the run to fit the cross.
"You've got to put yourself in positions and sense the space and then, obviously, on top of that, to finish it and show the composure.
"I think he's certainly done that this season."
Carrick added: "He's always scored important goals. He's always found himself there at certain times.
"He's scored good goals for us, important goals and not just this season."
