Fluminense Upon joining
Fluminense, Rafael was converted to play at
full-back by the youth team coach. Therefore, they decided to sign for Manchester United over Arsenal, and the two clubs agreed a deal in February 2007; the twins moved to Manchester in January 2008 without ever having played for the Fluminense first team.
Manchester United 2008–09 season The twins decided to sign for Manchester United, and a deal was agreed between the two clubs in February 2007. The twins moved to Manchester in January 2008, but were unable to play in matches until they turned 18 in July 2008. Rafael made his first appearance for the club in a 2–0 friendly win over
Peterborough United on 4 August. Rafael was then registered in the club's senior squad for the
2008–09 season and was assigned the number 21 shirt. Rafael made his competitive debut for Manchester United on the opening day of the
2008–09 Premier League season, replacing
Fraizer Campbell in their 1–1 home draw against
Newcastle United on 17 August. Rafael's first start for Manchester United came on 23 September in their 3–1 home victory over

Blackburn Rovers On 27 October 2009, Fábio, Rafael's twin brother, was booked for a foul committed by Rafael in United's 2–0
League Cup victory over
Barnsley. Manchester United appealed and
The FA agreed it was a case of mistaken identity, transferring the card over to Rafael. On 30 December, Rafael scored the second goal of his Manchester United career and the first at
Old Trafford in a 5–0 league win over
Wigan Athletic. On 7 April 2010, Rafael was sent off for the first time in his United career, receiving two yellow cards either side of half-time against
Bayern Munich in the second leg of the Champions League
quarter-final tie. Despite United winning the game, they were eliminated from the competition due to the
away goals rule when the aggregate score was 4–4. Despite this red card, Sir Alex Ferguson praised Rafael for his performance and stated that "he absolutely dominated
Franck Ribéry".
2010–11 season On 16 January 2011, Rafael was sent off for a second occasion, collecting two bookings in a 0–0 league draw against
Tottenham Hotspur at
White Hart Lane. Rafael received an £8,000 fine and a warning about his future conduct by The FA following his red card. Rafael suffered a concussion in United's 3–2 away victory over
Blackpool on 25 January, the match following his one-game ban, and was taken to hospital for
X-rays before later being released. Rafael collided with Blackpool's
Marlon Harewood during the second half, which resulted in ten minutes of stoppage time, and forced Rafael out of United's FA Cup tie away to
Southampton on 29 January.

Community Shield victory back in August against
Crystal Palace in the League Cup on 20 November 2011, a game which United lost 2–1 in extra time. On 31 December, Rafael started his first league game of the season against
