A way of adjusting stats to account for how much the ball a team has. A team with 70% possession will naturally have more passes, so comparing their passing numbers directly to a team with 40% possession is misleading. Possession-adjusted stats divide by possession share to give a fairer comparison. Useful for evaluating defensive actions especially - making fewer tackles might just mean you have the ball more often.

An unbroken chain of passes before the ball is lost. Sequences can be long (tiki-taka style) or short (direct football). Teams are judged on how many long sequences they produce and what they do with them. A 15-pass sequence that ends with a sideways ball is different from one that ends with a shot. The quality of the sequence's endpoint matters as much as the length.

A measure of pressing intensity. Divide the passes you allow by the defensive actions (tackles, interceptions, fouls) you make in the attacking third. Lower number means more aggressive pressing - you're intervening more often. Higher number means you're sitting off and letting them pass. It's a standard stat now for measuring how much a team presses, though it doesn't tell you how well organized that pressing is.

The pass before the assist. Player A passes to Player B, who passes to Player C, who scores - Player A gets the pre-assist. It's a way to give credit to players who set up the setup, especially playmakers who create the opening without getting the final ball themselves. Not an official stat but tracked by analytics sites and used to identify creative players.

An agreement to sign for a new club that can be made when a player has six months or less on their current contract. The player sees out their deal, then joins the new club on a free. Big clubs hate it because they lose valuable players for nothing. Players and agents love it because all the money that would've gone to the selling club can go into wages and signing bonuses instead.
