For people saying Kane goes down early, I agree he does, but that is because he is trying to make sure the contact doesn’t hurt him & that he is in control of his fall We cannot penalise for not wanting an injury, if we force them to maintain their normal gate they will get hurt 2.3K views · 14 likes · 0 reposts · 2 replies Open on X →

If refs consistently get this wrong (like the Saka vs Neuer one and the Haaland vs Sels one) then it will reduce the skill in goalkeeping as all goalkeepers when an attacker is 1v1 will sprint at the attacker then pull their hands back and they will become nearly unbeatable! 4.4K views · 16 likes · 1 reposts · 2 replies Open on X →

An attacker is perfectly entitled to knock the ball to the side (given that is the only option you have given them) and take the contact. If you are out of control you run the risk of giving away a penalty! 3.9K views · 13 likes · 1 reposts · 1 replies Open on X →

Sprinting forwards & throwing your body across to minimise the size of the goal when facing a 1v1 100% impedes an opponent’s ability to score the chance, even if at the last sec you tuck your arms in, so if you do it you better get the ball or stay a few yrd from the attacker! ht
