David Robert Edmund Button (born 27 February 1989) is an English professional footballer who plays as a goalkeeper for EFL League One club Reading.

[5] An injury to second-choice goalkeeper Heurelho Gomes saw Button receive his first call-up to senior team substitutes' bench early in the 2009–10 season for a 2–1 Premier League win over West Ham United on 23 August 2009.

[5][6] Button made his debut in the following game, replacing Carlo Cudicini after 81 minutes of a 5–1 League Cup victory over Championship side Doncaster Rovers.

[20] Button joined fellow League Two side Luton Town on a one-month loan deal on 6 March,[21] and was an unused substitute on seven occasions.

[23] Button was, unusually for a goalkeeper, handed the squad number 6 and made his debut for the club in the 3–0 home victory against Bradford City on 18 April.

[20] Button joined League Two side Crewe Alexandra on a one-month loan on 22 July 2009 and he played in the first three games of the season,[24] keeping two clean sheets.

[32] Playing for the first time at League One level, injuries from September through to November disrupted his spell and he was dropped on 22 February 2010 after an eight-game losing run.

[5] Button managed to oust Romain Larrieu as number-one and regain his place in early April,[33] though his efforts were in vain as Plymouth finished 23rd and suffered relegation to League Two.

[37] On 1 January 2012, Button left Leyton Orient and joined Championship side Doncaster Rovers on a one-month loan,[37] which was later extended by another month.

[39] On 19 March 2012, Button joined fellow Championship side Barnsley on an emergency loan deal, to cover for the injured David Preece.

[45] The departure of Simon Moore to Cardiff City and injury to Richard Lee saw Button begin the season as manager Uwe Rösler's first-choice goalkeeper.

[49] An open forum between players and management in the dressing room after a 2–1 defeat to Stevenage on 12 October saw a turnaround in the team's fortunes and the beginning of a run of nine consecutive wins in the league,[50] with Button appearing in eight of those matches and keeping seven clean sheets.

[66] Button made his debut for the Sussex club in an EFL Cup tie against south coast rivals Southampton on 28 August 2018 where Brighton lost 1–0 at Falmer Stadium with Charlie Austin netting the only goal of the game.

[70][71] He played in their next league cup game six days later where West Brom lost on penalties at home to Button's former club Brentford after a 3–3 draw at full time.

[76] After Sam Johnstone was sent off after the final whistle in the 1–1 home draw against Cardiff City on 2 January 2022, Button won some game time and played in several consecutive matches.

Button kept his place in goal after Johnstone's suspension was over with head coach Valerien Ismael keeping the first choice keeper out due to an internal issue.

In the 4–0 home victory over already relegated and his former loan club Barnsley in the last game of the season, Button assisted Adam Reach's goal with a long range pass with West Brom sealing 10th place.
