Answer
Sven-Goran Eriksson was the coach of England when Theo Walcott played in the 2006 World Cup. Eriksson was appointed as England manager in 2001 and led the team to the quarter-finals of the 2002 World Cup and the final of Euro 2004. However, he was sacked after England's disappointing performance in the 2006 World Cup, in which they were knocked out in the first round.
