The Phoenix Suns are finalising an agreement with former NBA champion coach Frank Vogel to become their next head coach, according to multiple reports.

Vogel, who guided the Los Angeles Lakers to an NBA title during the pandemic-shortened 2019-20 season, takes over a talent-laden Suns team that has compiled a 160-76 record over the last three regular seasons - the highest winning percentage in the league over that period - but still seeks the first championship of the franchise's 55-year existence.

The 49-year-old replaces Monty Williams, who was fired shortly after the Suns were ousted by the Denver Nuggets in six games in the second round of the Western Conference playoffs.

Williams was hired as the Detroit Pistons' head coach earlier this week. The 2021-22 NBA Coach of the Year went 194-115 over four seasons in Phoenix and led the Suns to the 2021 NBA Finals.

Vogel owns a 431-389 overall record over 11 seasons with three different teams along with a career 49-39 playoff record. His greatest success came during his first season in Los Angeles, where a Lakers team led by superstars LeBron James and Anthony Davis went 52-19 before winning four playoff series in the Orlando bubble to earn the Larry O'Brien Trophy.

The Lakers failed to follow up on that success, however, losing to the Suns in the first round the following season. Vogel was then fired after the 2021-22 campaign in which Los Angeles went a disappointing 33-49 and missed the playoffs. 

Regarded as a defensive specialist, Vogel previously directed the Indiana Pacers to five playoff appearances - including two trips to the Eastern Conference finals - over a six-year stretch from 2010-16. He also served as the Orlando Magic's head coach from 2016-18.

Vogel will again be taking over a team with two bona fide stars in Phoenix with Kevin Durant and Devin Booker locked into long-term deals, though the Suns do have offseason decisions to make on two other key players. Veteran point guard Chris Paul turned 38 in May and has a partially guaranteed contract for next season, while center Deandre Ayton struggled in the playoff series against the Nuggets and sat out Denver's clinching victory with a rib injury.
