Speaking to the club's official website Carrick said the 25-year-old has had no issues in settling in at the club.
"Yeah, he feels at home in this weather!" Carrick said. "It's what he's used to, but yeah he's settled in really well. He's an intelligent, smart lad and speaks great English so it's been pretty seamless so far.
"There's plenty of Portuguese-speaking (players) anyway. But he's fine, he's settled in really well and he'll just be looking to get games under his belt now and improve as time goes on.
"I think the main thing is his composure and quality on the ball. He sees a pass, he looks to play the pass and he can score goals.
"But it's more that composure, understanding of the game and game intelligence really that I like the most about him, and I'm sure we'll see plenty of that."
