responsible for Boavista FC's greatest ever success, the league championship in 2001, followed by a participation in the second group stage of the UEFA Champions League and a 2002–03 UEFA Cup semi-final run. These achievements prompted the interest of La Liga club RCD Mallorca in June 2003, but he was dismissed in September after just five matches and one win, immediately returning to Boavista as a replacement for sacked Erwin Sánchez, whom he had previously managed there. Following a poor run of results, Pacheco stood down in April 2005. He was then contracted by Vitória Guimarães but resigned in December, after which he again moved to his main club. Pacheco was at Boavista's helm when the Porto team were relegated to division two at the end of the 2007–08 season, due to the Apito Dourado affair. He then signed with C.F. Os Belenenses, but left by mutual agreement in May 2009 as the Lisbon side were eventually relegated – later reinstated. Pacheco joined Al Shabab FC (Riyadh) in 2009, winning the Prince Faisal bin Fahad Cup almost immediately. However, following a 0–1 group stage loss against Iran's Sepahan F.C. for the campaign's AFC Champions League on 15 April 2010, he was relieved of his duties. In December 2010, Pacheco was signed by Beijing Guoan F.C. of the Chinese Super League on a year-long contract. In June of the following year, during a match against Tianjin Teda F.C. at Workers Stadium, he erected his middle finger to the referee and the opposite team, being punished with an eight-match suspension and a €4,265 fine by the Chinese Football Association. Pacheco moved to the third continent of his career in October 2014, when he was appointed at Egypt's Zamalek SC as a replacement for the dismissed Hossam Hassan. At the turn of the new year, he unexpectedly quit the league leaders to return to Al-Shabab; he had a record of eight wins and a draw from ten games and felt disrespected by the club's board. His second spell in Riyadh lasted just until March 2015, when he left by mutual consent to deal with undisclosed personal issues at home. In August 2016, Pacheco returned to China's top flight by agreeing to a one-year deal with Tianjin Teda. Having completed his goal of keeping them in the league that year, he left the next May after a five-game winless run in the opening stages
