Problem: Background: Hasek started playing hockey at the age of six in his native Czechoslovakia. As he explains: They held a tryout for 5-year-old boys and my father took me there. I didn't even have real skates. I had those blades that you screwed onto the soles of your shoes, but I was tall, and the 9-year-olds didn't have a goalie, so they put me in with them and thats where I fell in love with the game of hockey.
Context: After his contract with the Red Wings expired, Hasek announced his intention to play for a Stanley Cup contender, and specifically named the Ottawa Senators as a possibility. On July 6, 2004, after trading Patrick Lalime to the St. Louis Blues, the Senators signed Hasek to a one-year deal.  During the 2004-05 NHL lockout, Hasek toured with the Primus Worldstars. Similar to the tour Wayne Gretzky and IMG formed during the 1994-95 NHL lockout, the Primus Worldstars Tour ran December 7-23, playing in seven different countries (Riga, Latvia; Moscow and St Petersburg, Russia; Bratislava, Slovakia; Bern, Switzerland; Karlstad, Jonkoping and Linkoping, Sweden; Oslo, Norway; Katowice, Poland) in ten scheduled games. The tour competed against all-star teams or club teams of each country.  Hasek played increasingly well for the Senators up until the 2006 Winter Olympics in Turin. During the season, he reached 300 career wins, and his GAA and save percentage were the second-best in the league. Upon departure to Turin, Hasek's equipment was accidentally left behind in Ottawa. This caused Hasek to miss a number of practices with the Czech national team. At the Winter Olympics, he injured his right adductor muscle while making a save in the first qualifying match against Germany, forcing him to leave the game after only 9 minutes and 25 seconds. Hasek's injury caused him to miss the rest of the regular season and post-season, despite several rumours that he would return in time for the playoffs. He said that if he were to be re-signed, he would play for a base salary of $500,000 with bonuses.  After the Senators were eliminated in the second round, they opted not to re-sign Hasek.
Question: when did he join the Ottawa senators?
Answer: On July 6, 2004,

Background: Larsson was born in Helsingborg, Scania. His father, Francisco Rocha, is from Cape Verde, and his mother, Eva Larsson, is Swedish. His parents, who never married and split up when he was 12, decided that he should take his mother's surname because they felt it would make it easier for their son to be accepted in Sweden. He credits his father for his love of football.
Context: At the end of the 2003-04 season, Larsson left Celtic on a free transfer and signed a one-year contract with Barcelona with an option for a second year. Larsson's contribution in Barca's La Liga win in his first season there was disrupted by serious injury. He scored 3 goals in 12 Liga games and one goal (against his former club Celtic) in four Champions League matches. After the match against Celtic, he said: "It was very difficult for me to celebrate my goal because I had so many great times here." On 20 November 2004, during the 3-0 victory in El Clasico against Real Madrid, Larsson tore the anterior cruciate ligament (ACL) and meniscus in his left knee. Despite his injury-hit 2004-05 season, playing only 16 games, Barcelona took the option to extend his contract.  In December 2005, Larsson announced that at the end of his contract, which ended in July, he would leave Barcelona and return to Sweden to end his career. He revealed that he had refused an offer by club president Joan Laporta to extend his contract to the end of the next season. On the announcement of his departure, Ronaldinho said:  In Larsson's final match for Barcelona, his substitute introduction was pivotal to win the 2006 Champions League final. Larsson assisted both of Barcelona's goals in a 2-1 win over Arsenal. Thierry Henry paid tribute to Larsson's contribution to Barcelona's win after the match, saying, "People always talk about Ronaldinho, Samuel Eto'o, Ludovic Giuly and everything, but I didn't see them today, I saw Henrik Larsson. He came on, he changed the game, that is what killed the game. Sometimes you talk about Ronaldinho and Eto'o and people like that; you need to talk about the proper footballer who made the difference, and that was Henrik Larsson tonight." Indeed, his ability to give Barcelona the cutting edge required to overcome Arsenal was noted by the international press. In 2005-06, Larsson scored ten goals as Barcelona won La Liga for a second consecutive year.
