It should not be a red card, though in modern football those kind of challenges is. Yeah of course i know the leg will probably snap if you miss the ball but thats part of the game. And i didn't quite get the part where you said as a Arsenal fan i should know better? Which club you support should be pretty irrelevant on your opinions on football. Back in the day those type of tackles would make a free kick at most. Nowadays you get booked for everything. Including celebrating in front of the opposition fans. WHAT THE HELL? Or something like taking your shirt off i mean come on. And its so much diving and going to the ground intentionally so yes it has become a pansies game. One of the few teams not being pansies left are Stoke City, proper lads.
I've recently re-watched Falmini's red-carded tackle and for me it has to be a sending off, if not a heavy yellow card. It was an irresponsible tackle, not only because it was two-footed with the studs up but because he probably would have won the ball without the lunge. I'm very disappointed with it, and now we have 3 titular midfielders out. Way to go buddy.
Direct red or not?
