in added extra time, after a goalless 90 minutes. The 2014–15 season was also a successful one for Basel, but for Díaz it was an unlucky and unthankful season under their new trainer Paulo Sousa. Despite the fact that Basel won the championship later that season and despite the fact that Basel had entered the Champions League in the group stage reaching the knockout phase on 9 December 2014 as they managed a 1–1 draw at Anfield against Liverpool, Díaz totaled just 24 appearances, the larger part as substitute, during the first half of the season, 13 (from 18) League, 2 Cup (of 3), and just 3 (of 6) in the Champions League, as well 6 further appearances in test games. Because Sousa did not rely upon Díaz, he was forced to leave the club during the winter break. On 2 February 2015 Basel announced that Díaz had joined Hamburger SV. During his time with the club, Díaz played a total of 118 games for Basel scoring a total of 15 goals. 58 of these games were in the Swiss Super League, 10 in the Swiss Cup, 51 in the UEFA competitions (Champions League and Europa League) and 19 were friendly games. He scored seven goals in the domestic league, two in the cup, four in the European games and the other two were scored during the test games. Hamburger SV On 2 February 2015, Díaz signed for German Bundesliga club Hamburger SV on a three-and-a-half-year deal. On 1 June 2015, he scored his first goal for the club in its relegation play-off match which took place at the end of the 2014–15 Bundesliga season, against Karlsruher SC. Many Hamburg fans consider Díaz's 91st minute free-kick goal which helped save Hamburg from its first ever relegation to be one of the most important goals ever scored in the club's 128-year history. After the match, it was revealed that Rafael van der Vaart, Hamburg's captain and first choice for free-kicks, was to take the kick. Diaz, however, spontaneously told Van der Vaart that he could take a shot "tomorrow, my friend" and went on to perform the free-kick himself. Celta de Vigo In January 2016, Díaz transferred to Spanish La Liga side Celta de Vigo. He scored his first goal for the club on 16 April 2017, in a 3–0 away win against Granada CF. On 17 August 2017, Díaz left
