A way of rating overhead kicks by comparing them to Trevor Sinclair's famous effort for QPR against Barnsley in the 1997 FA Cup. Sinclair's volley was hit from outside the box, and flew into the back of the net. It's the gold standard. So when someone pulls off a bicycle kick, you place it on the Sinclair Spectrum to judge how good it actually was. Popularised by Max Rushden on the Guardian's Football Weekly podcast.

Fabrizio Romano's catchphrase for confirming a transfer is done. When he posts on social media "Here we go!" it's a sure fire way of knowing a deal is agreed. It's become the unofficial official announcement in football - fans refresh his account constantly during transfer windows waiting for those three words.

Scoring two goals in one game. The word originates from hunting, where a brace meant a pair of birds. Less celebrated than a hat-trick but still a strong individual performance.

A player so good they only come along once in a generation. Gets overused - not everyone can be generational or the word loses meaning. True generational talents change the game and dominate for years. Messi, Ronaldo, Mbappé fit the definition. Calling every promising youngster generational has become a running joke because it happens so often now.

The last day of a transfer window when clubs can sign players. In England, windows close at 11pm on deadline day in summer (late August/early September) and winter (late January/early February). Sky Sports turned it into a TV event with reporters standing outside training grounds waiting for cars to arrive. Most deals get done in the final hours, with agents and clubs scrambling to submit paperwork before the deadline.
