Lose One's Way Meaning

Example: 2011 March 1, Phil McNulty, “Chelsea 2 - 1 Man Utd”[1], BBC:
  This was a wonderful advert for the Premier League, with both Chelsea and United intent on all-out attack - but Ferguson will be concerned at how his side lost their way after imperiously controlling much of the first period.
