On 25 February 2019, Grau was sacked with his team in last place and five points inside the relegation zone. His final game was a 3–2 home defeat to Lleida.[3]
Pafos
Grau told his agency Wasserman that he wanted to manage abroad, and he was appointed as an assistant manager at Pafos in the Cypriot First Division. He served under managers Dmytro Mykhaylenko and Stephen Constantine. Unlike many managers working abroad, Grau took his wife and infant daughter to Cyprus, citing the island's low crime rate and presence of the English language.[4]
Inter Turku
In November 2021, Grau signed for Inter Turku of the Finnish Veikkausliiga, succeeding compatriot José Riveiro on a two-year contract with the option of a third.[5] He reached the final of the Finnish League Cup, losing 3–1 on 19 March to Honka, as well as losing the Finnish Cup final 1–0 to KuPS on 17 September. He was sacked two days later, with his assistant Ramiro Muñoz overseeing the last five games of the league season with the team in 5th.[6]
Grau said that Finnish footballers were "methodical" and "mechanical" and needed the creativity of foreign players, which became more complicated due to points deductions for not fielding enough nationals in a team. He said that several players left in June at the halfway point in the season, and when they were preparing for a UEFA Conference League qualifier.[4]
