Jacob Harry Maguire (born 5 March 1993) is an English professional footballer who plays as a centre-back for Premier League club Manchester United and the English national team. Born in Sheffield, he came through the youth system at Sheffield United before graduating to the first team.
Maguire was born in Sheffield, South Yorkshire. After coming through the youth system at Sheffield United, and with the side struggling against relegation, he was promoted to the first team squad, making his debut after coming on as a half-time substitute and winning the man of the match award in a home game against Cardiff City in April 2011. He made four further appearances that season but could not prevent the club from slipping into League One.
Having cemented his place in the first team Maguire scored his first goal for the Blades in a 2–0 win at Oldham Athletic on the opening day of the 2011–12 League One season. Having been ever present from the start of the season Maguire was handed an extended deal in October to keep him at Bramall Lane until 2015. He continued in great form as the Blades pushed from promotion from League One and was rewarded at the end of the season when he was named as both "Player of the Season" and "Young Player of the Season" by the club. The BBC's Match of The Day magazine selected Maguire in its League One Team of The Year for 2011–12.
Maguire went into the following season as first choice in the centre of defence and his good form continued as he scored a brace in a Football League Trophy tie in a 4–1 victory over Notts County at Meadow Lane on 17 October 2012. By the end of February 2013 Maguire had made his 100th start for the Blades in a 0–0 draw against Leyton Orient at Bramall Lane at the age of just 19.
On 21 June 2014 it was revealed that United had offered Maguire an improved contract amid interest from Hull City and Wolverhampton Wanderers in signing Maguire with United already rejecting a £1 million and an improved £1.5 million bid from Wolves.
