Sir Alex Ferguson has hailed the progression that young full-back Rafael has made at Manchester United.
The 21-year-old has enjoyed an extended run in the United starting lineup of late, keeping the likes of Phil Jones and Chris Smalling on the sidelines.
Reflecting on the Brazilian's development in four seasons at Old Trafford, Ferguson was full of praise for the way he has adapted to the English top flight.
"He's doing well. He was always a rash, young boy and his enthusiasm was overwhelming at times but he's settled down quite well and is quite calm in his game now," Ferguson told the club's official website.
"So, by doing that, he's brought his game to a really good pitch at the moment.
"He's playing really well and combined well with Valencia. There's a good understanding there."
Rafael spent his youth career in his native Brazil will Fluminense.
