Cleveland Cavaliers forward LeBron James feels that his side did just enough in their clash against the Boston Celtics to secure a narrow 122-121 victory.

The 29-year-old scored 41 points in the match, but the Cavaliers were forced to come from 19 points behind in the fourth quarter to claim the win after allowing Boston to net 42 points in the third.

James told reporters: "We gave up a 40-point quarter and that's unacceptable if we want to grow, but we showed growth in the fourth quarter."

David Blatt's side moved to 4-3 in their season with the victory at the TD Garden.
