Chelsea beat a number of Serie A sides, including Inter, to sign the 18-year-old Brazil full-back from Fluminese for a fee of around £4.4 million in December 2012. He stayed on loan in his homeland until the summer of 2013 when he moved to the club.

Wallace only made his Fluminense debut as a 17-year-old in July 2012, just months after helping Brazil's U-17 side to the South American championship in Mexico.

The attacking full-back was key as Fluminense won the title for second time in three years and former Chelsea midfielder Deco recommended him to the Blues, who swooped quickly to ensure that his future was with them.

Strengths: Fast and agile, he has tons of stamina and an attacking philosophy down the flanks.

Weaknesses: Young and inexperienced, his positional sense is not honed as it could be and he can improve his decision making.

Career high: Winning the title with Fluminense in his first full season in the first-team.

Career low: He was a part of the Brazil side who only managed a fourth-placed finish at the Under-17 World Cup in Mexico in 2011.

Style: Quick, consistent, a defender of real potential.

Quotes: "My aim is to play a lot in 2013. After having participated in the pursuit of two major titles in 2012 [both national and state championships), next year, I want to win the Copa Libertadores [South America's Champions League]." Wallace in 2012.

Trivia: The European champions reportedly acquired a 40% stake in Wallace as part of the deal that took Brazil-born Portugal midfielder Deco from Chelsea to Fluminense in 2010.
