Newcastle United have appointed 38-year-old German coach Matthias Jaissle as their new head coach on a four-year deal, succeeding Eddie Howe, who stepped down after leading the club to a first trophy in decades. Jaissle arrives without prior Premier League experience but built his reputation with successes at Red Bull Salzburg in Austria and Al-Ahli in Saudi Arabia, and he takes charge as Newcastle attempt to rebuild after losing several key players, including captain Bruno Guimaraes, who is joining Arsenal.

Jaissle becomes the Premier League's second-youngest current head coach and will make his competitive debut against Liverpool on 23 August. Having already joined the squad's pre-season training camp in Spain, he is described by those who have worked with him as demanding and detail-oriented, expecting high intensity in training and willing to challenge players directly. He inherits a squad that has become notably younger this summer, though experienced figures such as Dan Burn and Fabian Schar remain, and his task will be to develop talent while competing against better-resourced rivals following a 12th-place finish last season.
