France v Uruguay was as gritty as many predicted.After showcasing the beautiful game in their 4-3 win over Argentina, Les Bleus faced a completely different prospect in the quarter-final.Oscar Tabarez's side are widely regarded as the Atletico Madrid of the international scene and they lived up to their reputation.There were snapping tackles and off-the-ball incidents, but France came through it all to secure a 2-0 win.Real Madrid's Raphael Varane gave the European side the lead with a lovely header from Antoine Griezmann's free-kick.Griezmann then added the second shortly after half-time, courtesy of a dreadful error from Uruguay keeper Fernando Muslera.The shot was tame, but he somehow managed to parry it into the net.As Gary Neville said in commentary, Muslera actually moved outside the line of the ball.

Probably the worst goalkeeping error of the tournament. Well, at least on par with Willy Caballero.

Naturally, the reaction on Twitter focused on Liverpool's Loris Karius, who made a very similar error in the Champions League final.

The German spilled Gareth Bale's long-range effort to effectively hand the game to Los Blancos.

After that game, it was revealed that Karius had actually picked up concussion following a clash with Sergio Ramos.

And as such, BBC presenter Gary Lineker made a bit of a joke about the incident.

LINEKER'S TWEET

While it's clearly a bit of a joke, someone of his standing in the footballing community probably shouldn't be mocking concussion.

As such, football fans were not too happy with the usually popular Twitter figure.

FANS REACT

Given the issues with concussion already at this tournament, particularly with Morocco's Nordic Amrabat, this was probably a subject best avoided.
