Kieran John Trippier (/ˈkɪəˌrɔːn ˈtrɪpjər/;[3] born 19 September 1990) is an English professional footballer who plays as a right-back for Premier League club Newcastle United.

Trippier started his career in the youth system at Manchester City but failed to make the breakthrough to the first team, having two loans at Championship club Barnsley.

After four years in North London, during which he became part of the squad that finished as runners-up in the 2019 Champions League final, Trippier joined Spanish side Atlético Madrid, where he helped the team win the 2020–21 La Liga title.

He made his debut for the senior international team in June 2017 and played in the 2018 FIFA World Cup, where he scored directly from a free kick in the semi-final.

[19] He scored his first senior goal for Barnsley in a 3–3 draw with Leeds United, with a curling free kick from 25 yards out at Elland Road in February 2011.

[25] His first goal for the club came in September 2011, with a superb long-range free kick against Milton Keynes Dons in a 2–1 win in the League Cup.

[26] His first league goal came in December 2011, a 1–0 win over Brighton & Hove Albion at the Falmer Stadium, with a powerful shot from the edge of the box.

[36] He was again named in the Championship PFA Team of the Year for consecutive seasons[37] as Burnley finished runners-up and gained promotion to the Premier League.

[39][40] Trippier was expected to compete with Kyle Walker at right-back under manager Mauricio Pochettino, and he did not make a start for Tottenham before Christmas as he was eased into the team.

[42] Trippier appeared in six games for Tottenham during the Premier League season, making five starts as Walker displayed his best form in recent years.

[45] He performed well in the right-back position as replacement for Kyle Walker who was injured during the 2016–17 season, and earned his first call-up for the England national squad.

[49] He impressed with his performances in the season, in particular during the UEFA Champions League home match against Real Madrid on 1 November 2017, which Spurs won 3–1.

[51] However, it was generally considered that he had a disappointing season, after suffering from a series of minor injuries,[52][53] as well as having committed a number of defensive errors.

[60] Trippier signed for La Liga club Atlético Madrid on 17 July 2019 on a three-year contract, for a fee of £20 million plus add-ons.

[63] In his debut on 18 August in their opening La Liga match against Getafe, he helped the team to a 1–0 home win by providing an assist for Álvaro Morata's goal.

[65][66] Atlético requested a review and the ban was suspended by FIFA until the case was decided by the Court of Arbitration for Sport (CAS).

[72] On 7 January 2022, Trippier signed for Premier League club Newcastle United on a two-and-a-half-year contract for a fee of £12 million plus add-ons.

[76] On 13 February, after scoring a second goal for the club, also a free kick, in a 1–0 home win against Aston Villa, Trippier broke his foot.

[81] In the 2022–23 season, Trippier was a key member of the Newcastle team that reached third place in the Premier League at the November break, receiving regular praise from pundits for both his defensive and creative skills.

[84] On 24 September 2023, Trippier played in Newcastle's 8–0 win at Sheffield United; he became the second player in Premier League history to assist three headed goals in a match.

[12][88] He then progressed to the under-19 squad in November 2008 for the 2009 UEFA European Under-19 Championship qualification match against Albania, making his debut in the 3–0 win in Coleraine, Northern Ireland.

[95] Trippier was called up to the senior team for the first time in May 2017 for the 2018 World Cup qualifier against Scotland and the friendly match against France,[96] making his debut against the latter on 13 June in a 3–2 defeat.

[99] He was widely praised as one of the best performers for the England team at the World Cup,[100][101][102] particularly for his crosses and dead-ball delivery on set pieces, prompting comparison with David Beckham.
