As soon as Burton is about to make contact, it’s bend, shrug and buckle at an angle. He’s the best at it by a mile , I’ll give him that, but it’s not a free kick.
That is one way of looking at it, but he was also trying to evade a hawk player in front of him, and when he turned Burton laid a tackle.. Was he off balance because his weight shifted when contact was made? It's hard to judge, because people only believe what that want to see..
