Push the ball one way with the outside of your foot, then snap it back the other way with the inside of the same foot, all in one motion. Also called the flip-flap or snake. Creates the illusion of going one direction before exploding the other way. Ronaldinho made it famous, though Rivellino and Sérgio Echigo were doing it earlier. At speed, it's almost impossible to defend.

Dribbles that move the ball at least 10 yards toward the opponent's goal or into the penalty area. It separates players who carry with purpose from those who just run sideways. Wingers and ball-carrying midfielders stack up numbers here. A high progressive carry count means you're beating players and advancing the ball, not just keeping possession.

Passing the ball through an opponent's legs and collecting it on the other side. Also called "panna" in street football or "megs" in British slang. It's embarrassing for the defender and always gets a reaction from the crowd. You need good timing and sometimes a feint to open their legs. Nobody's quite sure where the name comes from - theories include Victorian nutmeg trading slang and cockney rhyming slang.

How good the backup players are when starters get injured or rested. Deep squads can rotate without losing quality. Shallow squads fall apart when key players are missing. Manchester City's depth means their B-team could challenge for titles; smaller clubs rely on 11 players and pray they stay fit. Modern football's congested schedule makes depth more valuable than ever.

Arsenal's 2003-04 squad that went the entire Premier League season unbeaten: 26 wins, 12 draws, 0 losses. The first team to do it in modern English football. Arsène Wenger built a side mixing French technique (Henry, Pires, Vieira) with English grit. The unbeaten run reached 49 games before Manchester United ended it in October 2004. It's hard to imagine anyone doing it again.
