Running inside a teammate who has the ball wide, usually into the gap between full-back and centre-back. The opposite of an overlap - you go inside rather than around the outside. It pulls defenders, opens passing angles into the box, and can create shooting chances. Works well with inverted wingers because when they cut inside, they create space for the underlap.

Diving forward and flicking the ball with your heels behind you, legs bent like a scorpion's tail. The opposite of a bicycle kick, which goes backwards. Extremely rare because the situation has to be exactly right and it's incredibly hard to pull off. When it goes in as a goal, it wins every award going. Giroud's against Crystal Palace in 2017 won the FIFA Puskás Award.

Striking the ball with the end of your boot rather than your laces or instep. Coaches used to tell kids never to do it because it's inaccurate, but sometimes it's the only way to get a shot off quickly. When a defender is about to block or the ball is bouncing awkwardly, a toe poke can surprise the keeper because the shot comes out faster than expected.

Carefully controlling how much a player plays to prevent injuries. Involves resting players who've played too many minutes, monitoring training loads, and sometimes sitting out less important games. Modern sports science tracks everything. Fans complain when their best players get rested, but the alternative is burning them out. The fixture congestion in modern football makes it more important than ever.

Striking the ball with the outside of your foot to bend it in an unexpected direction. Ricardo Quaresma made the trivela famous as his signature move in Portugal. It's tricky to pull off but useful for curving passes or shots around defenders when the inside of your foot won't give you the right angle. Modrić and Cancelo use it regularly now.
