After Cheick Tiote's amazing strike was ruled out for Newcastle against Manchester City, we dug out 10 of the greatest disallowed goals.
1. Cheick Tioté - Newcastle v Manchester City, 2014
Tioté's spectacular strike would have brought Newcastle level at 1-1, but the home side were left fuming when it was ruled out for offside because Yoan Gouffran had moved out of the way of the shot while standing on the edge of the six-yard box.
2. Edinson Cavani - Napoli v Barcelona, 2011
What a goal this would have been. Cavani's overhead kick in the pre-season Joan Gamper Trophy rivals the best of its kind, but it never counted with the goal ruled out for Marek Hamsik's offside in the build-up.
Displaying stunning technique with his scissor kick, Keegan's effort flew into the top corner but was not allowed to stand due to an offside in the build-up.
4. Cristiano Ronaldo - Portugal v Spain, 2010
Nani you idiot. Having left his opposite number for dead, Ronaldo produces a lovely piece of trickery before dinking the ball over the Spain keeper's head and into the net... only to see his offside team-mate decide to head the ball over the line from approximately two inches out.
Years before he became a (now disgraced) TV pundit, Gray would have told himself to "take a bow" with this finish. However, the goal was not allowed to stand because a team-mate has strayed into an offside position, almost 15 metres away from action.
6. Thiago Silva - Paris Saint-Germain v Nice, 2013
What a spot from the assistant referee. Playing against Nice, PSG captain Silva scores what surely would have been a contender for goal of the season, only for it to be ruled out with the ball having crossed the line for a goal kick by about an inch.
7. Zico - Brazil v Sweden, 1978
The goal may not have been spectacular, but Zico's header (disallowed because the final whistle had already blown) is arguably the most high-profile on this list, coming in the final seconds of the 1978 World Cup group match with Sweden.
8. Don Hutchison - Everton v Liverpool, 2000
Another victim of the final whistle, Hutchison thought he had scored when Liverpool keeper Sander Westerveld booted a free-kick against the Everton player's back before flying into the net. But referee Graham Poll disallowed it, indicating that time was up.
9. Yoann Gourcuff - Lyon v Real Betis, 2013
The Frenchman's connection with the ball is second to none as it sails into the net from the halfway line, but the goal was never allowed to stand as the whistle had already gone for an earlier foul.
10. Michel Platini - Juventus v Argentinos Juniors, 1985
The future Uefa president scored one of the greatest ever disallowed goals in the 1985 Intercontinental Cup when he controlled the ball on his chest, lifted it over the defender with his right foot and volleyed home with his left, before wheeling away in celebration. Check out his pose when informed it doesn't count.
