Boyd was born in Germany, starting his career with the reserve teams of Hertha BSC and Borussia Dortmund, before a move to Austrian-based Rapid Wien in 2012 became the catalyst to kick start his career.
A consistent goalscoring striker, the 23-year old has scored 70 goals in 135 competitive appearances throughout his career, with 28 in 59 games for Rapid.
The powerfully built forward, who has previously been scouted by Liverpool, is seen as a great professional off the pitch - impressing teammates with his enthusiasm - as well as a remarkably talented goalscorer on it.
Despite his impressive record, he has failed to score for the USA national team in the 13 caps he has received. He received a call-up for Jurgen Klinsmann's 30-man preliminary squad for the 2014 World Cup, although he failed to make the final 23.
However, his rejection from the squad may work into his hands, as Championship side Wigan Athletic have opened talks with the player over a possible move to the DW Stadium.
The Daily Mail is reporting that Latics boss Uwe Rosler is prepared to offer Rapid £3 million for the striker, as he intends for him to lead the line in their search for promotion back to the Premier League.
The ageing Marc-Antoine Fortune and Grant Holt currently head the Latics attack, and the inclusion of the 6ft 2ins 23-year old will add youth to their ranks, without losing physicality in the process.
Wigan missed out on promotion in the late stages of the 2013/14 season, losing to QPR in the play-off semi-final as they searched for an instant return to the Premier League. Despite failing in their prime aim, it was a successful season following Rosler's appointment in December, playing attractive football as they reached an FA Cup semi-final.
As he looks to Boyd to improve his team, many will be hoping that the American is the key to secure a return to the Premier League.
