Premier League clubs used the new five-substitute rule to their advantage to help secure victories on the opening day of the season.
Newcastle United, Tottenham, Southampton and Chelsea were the only top-flight teams to make all five changes, with all but Saints going on to pick up three points.
Eddie Howe used all of his changes during three separate stoppages in the last 10 minutes as the Magpies saw out a 2-0 victory over Nottingham Forest.
Clubs are only allowed to make substitutions in three breaks in play in an attempt to stop clubs exploiting the rule to waste time.
