Kenneth Harold Vermeer (born 10 January 1986) is a Dutch professional footballer who plays as a goalkeeper for Eredivisie club PEC Zwolle.

[6] Due to an injury for teammate Maikel Aerts, Vermeer started as first-choice goalkeeper for Willem II, and made his Eredivisie debut for the club.

[13] Vermeer would play every remaining game that season as Ajax clinched their 30th Eredivisie title under new manager Frank de Boer.

Although he had a rocky start to the season by conceding six goals in a game at Utrecht and a weak shot in a match against Roda, Vermeer rebounded well and made the net his own following the departure of Maarten Stekelenburg.

[18] On 20 January 2013, during the Klassieker match against arch-rivals Feyenoord, Vermeer helped Ajax to a 3–0 victory at home, keeping a clean sheet while saving a penalty kick from Lex Immers in the 64th minute of the game.

[26] Following these events, Ajax manager Frank de Boer announced that he would give the precedence to the then second choice keeper Jasper Cillessen, while Vermeer could focus on his training and conditioning in order to obtain his form he had previously displayed.

[27] On 28 October 2013, Vermeer made his debut in the Eerste Divisie, the second tier of professional football in the Netherlands when he appeared in goal for newly promoted Jong Ajax in the 4–0 loss at home against FC Dordrecht.

[28] On 26 July 2014, Vermeer helped Ajax to a win the seventh edition of the Eusébio Cup at the Estádio da Luz in Lisbon, Portugal.

He saved 7 in a row by the end of the 2013–14 season, without conceding a penalty since 29 January 2012, when John Guidetti of Feyenoord managed to secure one for his side.

[36] He made his continental debut for his new club in Spain during the 2014–15 UEFA Europa League group stage in a 2–0 loss against Sevilla FC.

He was given the number 32 shirt, serving his loan spell as second keeper behind Vladimir Gabulov with Club Brugge leading the Belgian First Division A table by 11 points going into the second half of the season.

[39] On 15 January 2020, Major League Soccer club Los Angeles FC acquired Vermeer using Targeted Allocation Money.

On 1 March 2020, Vermeer made his Major League Soccer debut against inaugural club Inter Miami CF, which Los Angeles FC won 1–0.

[48] At age 20 he was called up to play for the Netherlands under-21 squad, making his debut on 24 May 2006 in the opening match of the 2006 UEFA European Under-21 Football Championship against Ukraine U-21.

Although the Netherlands lost the opening fixture 2–1, the Dutch would eventually win the tournament, marking the nation's first U-21 European Championship as they defeated the Ukraine U-21 by score of 3–0 in the final.

[51] On 2 August 2008, he made his debut for the Netherlands Olympic squad in a friendly match against Ivory Coast in preparation for the Summer games.

[53] On 5 October 2012, Vermeer received his first call-up from head coach Louis van Gaal for the 2014 FIFA World Cup qualifying matches against Andorra and Romania as a replacement for the injured Tim Krul.

[57] On 11 June 2013, Vermeer became the record holder for the Netherlands national football team, for the longest streak as a goalkeeper without conceding a goal.

[59] Louis van Gaal later insisted that Vermeer would have indeed been a better fit for his game plan, but that due to Cillessen showing better form, he opted for the latter instead.
