He was also head coach of the senior national team for two years, but was dismissed before the start of the2018 World Cup following the announcement of his agreement to join Real Madrid after the tournament. In club football, he managed Rayo Vallecano,Castilla,Porto, Real Madrid,Sevilla,Wolverhampton Wanderers andWest Ham United, winning the2020 Europa League with Sevilla.
On 8 January 2016, after a1–3 home loss toMarítimo in theTaça da Liga,[26] as Porto had already been eliminated from theChampions League and was ranked third in thedomestic league after an away loss and a home draw, Lopetegui was relieved of his duties and replaced byRui Barros.[27] A week later, the club announced that it had terminated the former's contract unilaterally.[28]
On 21 July 2016, after being strongly linked to English sideWolverhampton Wanderers which was under new ownership,[29] Lopetegui was announced as the new manager of the Spain national team followingVicente del Bosque's retirement.[30][31] In his first match in charge, on 1 September, he led them to a 2–0 friendly victory overBelgium at theKing Baudouin Stadium;[32] the nation qualified for the2018 World Cup, winning nine and drawing one of theirgroup matches.[33]

Lopetegui agreed to a further two-year extension on 10 January 2021.[45] On 5 October 2022, however, following five losses in eight matches in thenew season – the last being 4–1 at home againstBorussia Dortmund in theChampions League – he was dismissed.[46][47]
After leaving Sevilla, Lopetegui was interviewed by Wolverhampton, who had recently dismissedBruno Lage, but he initially turned down the offer due to his 92-year-old father's ill health.[48] He was approached again and, on 5 November 2022, announced he would become the club's new head coach effective 14 November.[49] On his competitive debut on 20 December, his team defeatedEFL League Two sideGillingham 2–0 at home in thefourth round of theEFL Cup;[50] this put them into the last eight for the first time since1995–96.[51] Six days later, on hisPremier League bow, they won 2–1 atEverton with a last-minuteRayan Aït-Nouri goal, and the manager thereby became the first at the club to win his opening match in the top flight sinceJohn Barnwell in 1978.[52]

Sporting directorMonchi, who worked with Lopetegui at Sevilla, described him as having three virtues that are fundamental for any coach: great professional qualities, competitiveness and group management. He also highlighted Lopetegui's fit to work in big clubs saying that 'Julen perfectly understands what a big club needs, he has his requests, but it’s normal, and he always works in sync with the club. He is demanding but only for the good of those who appointed him and never out of selfishness.'[68]
