LOS ANGELES: Two years after their traumatic World Cup semi-final exit, Brazil are haunted by the past as they head into the Copa America Centenario aiming for their first title in nearly a decade. In previous eras, Brazil would arrive at the Copa America brimming with confidence and the only debate would revolve around who they could expect to face and eventually defeat in the final. Between 1997 and 2007, Brazil won four out of five editions of the tournament, helping to make them the most successful nation since 1975, when the Copa America began to be held regularly after an eight-year absence. Yet as Brazil prepared to embark on this year’s tournament the familiar swagger is gone. The humiliating 7-1 thrashing by Germany in 2014 had left a team in search of an identity torn between a more pragmatic and defensive approach and the hardwired instincts towards flamboyance. So far, under the second managerial tenure of 1994 World Cup-winning captain Dunga, the results had been mixed. A quarter-final exit at last year’s Copa America in Chile had been followed by a stuttering start to South America’s marathon qualifying campaign for the 2018 World Cup.
