In 1981, Tatu came to the United States after playing with São Paulo. He had intended to play for several months, earning enough money to buy a house in São Paulo. Tatu signed with the Tampa Bay Rowdies of the NASL during the 1981–82 indoor season and scored a hat trick in his first appearance even though he had not yet had the opportunity to practice with his new club. He quickly became a fan favorite while playing several more outdoor and indoor seasons in Tampa Bay. He was a member of the Rowdies when they won the 1983 NASL Grand Prix of Indoor Soccer. The NASL folded in 1984, and Tatu moved to the Dallas Sidekicks of Major Indoor Soccer League. When Tatu moved to Dallas, the Cleveland Force sued the Sidekicks, arguing they had an agreement with him to purchase his contract from the Rowdies. The Sidekicks eventually gave the Force their second round 1985 draft choice. As a Dallas Sidekick, Tatu was a part of all four Sidekick's championship teams. From 1984 until 1992, the Sidekicks played in MISL. The league collapsed in 1992, and Dallas moved to the newly created Continental Indoor Soccer League until that league also collapsed in 1997. The CISL played during the summer, and Tatu spent the 1993–94 winter indoor season with the Wichita Wings of the National Professional Soccer League. In 1998, the Sidekicks competed in the Premier Soccer Alliance. The PSA became the World Indoor Soccer League in 1999. In 2002, Dallas entered the newly reconstituted Major Indoor Soccer League. Tatu retired from playing in 2003.
Coaching career
In 1998, Tatu replaced Gordon Jago as the head coach of the Dallas Sidekicks. Tatu is the only person to win the player of the year and the coach of the year in the same season. As a head coach, he went 63–53 in the regular season and 7–3 in the playoffs. Tatu also spent six years coaching at The Highlands School in Irving, Texas, where he coached the Blazers to three state championships in 1997, 1998 and 2000. The high school team which he coaches now is Prince of PeaceChristian School in Carrollton, Texas. He led the Prince of Peace varsity boys to seven TAPPS state championships: 2003, 2004, 2005, 2006 and 2009-2010, 2010-2011, 2011–2012. In the 2017–18 season, Tatu led his team to the TAPPS State Final Four where the Eagles lost during a torrential downpour against Brighter Horizons Academy. Tatu currently has also been coaching several girls' soccer teams for the Sting Soccer Club in North Texas. In April 2012, it was announced that the Dallas Sidekicks would return to the indoor game as part of the Professional Arena Soccer League for the 2012–13 season. Tatu was a co-owner of the team and served as both the team's general manager and head coach for the inaugural season. He would remain with the club for three seasons, leaving in 2015. Tatu, in 2010 blew through all competition from East to West Coast in many travel tournaments testing best-of-the-best from every part of the known soccer world. Sting 95' Royal, who were renamed to Sting '95 were a team who knew few defeats and crushed the competition winning a cornucopia of 1st Place Medals. In 2010, Sting '95 was challenged with 2 National Championships to contend with. ECNL was brand new at that time and NYSL was phasing out but still active. Overland Park, KS was the venue for the Final in the NYSL final. Sting won 1–0 under amazing skies and after a short victory dance, packed up quickly for the ECNL. 1st-time finals in Seattle the next week. They almost lost in the final match vs. a very tough team from California, but persevered to win at the end, earning 2 National Titles in one week. This feat has never been matched and never will. Incidentally, Sting '95 won ECNL National title the next year 2011. On 22 July 2019, Tatu was named the first-ever head coach for the Major Arena Soccer League's Mesquite Outlaws.
