[7] In a season that included a second stage, he ended with 43 league appearances, scoring seven goals; in his final year, he was part of the squad that lost the 1988 UEFA Cup on penalties to Bayer Leverkusen.
[14] He spent six seasons with the team, scoring 20 league goals from 1992 to 1994 before moving to Mallorca, where he was relatively used as the Balearic Islands club achieved top-flight promotion, and retired the following summer aged 33; during his time at Athletic, he was nicknamed Txingurri (Basque for ant).
[16] Immediately after retiring, Valverde began his career as a manager in the youth departments of former club Athletic Bilbao,[17] and four years later he became a co-trainer in the main squad.
[18] Heavily involved in the establishment of the club's women's team,[19] in 2002 he again acted as head coach when he took over the B side,[20] being promoted to first-team duties the following year;[21] in 2003–04, they finished fifth and qualified for the UEFA Cup.
[35] On 1 June 2013, immediately after the 4–3 away loss to Sevilla which meant Valencia could only finish fifth, thus out of qualification positions for the UEFA Champions League, Valverde announced he would leave the club.
[49] However, the team then went on a 29-match unbeaten run in all competitions from 20 August 2017 until 17 January 2018, when they lost to Espanyol in the first leg of the quarter-finals of the Spanish Cup (also the club's first defeat at the RCDE Stadium, home of their neighbours, since its 2009 opening).
[52] Barcelona remained undefeated for 43 matches in the Spanish League only to lose in their penultimate game of the campaign on 13 May 2018, having rested Lionel Messi for the trip to Levante – they were beaten 5–4 by the hosts.
[55] In February 2019 Valverde signed a new one-year contract extension,[56] as they went on a 23-match unbeaten streak and secured a second consecutive league title under him in April following a victory over Levante.
[57] He led his team to their first Champions League semi-final after a gap of three years, winning 3–0 at home against Liverpool but being eliminated after a 4–0 defeat at Anfield in the second leg, leading many to call for his dismissal.
[65] In his second season, he won the club's first major trophy in 40 years after beating Mallorca on penalties to claim the Spanish Cup, and also would have qualified for Europe via a fifth-place finish in the league.
