It was a straight red. Doesn,t matter about Naymar's reaction.
Brown was an absolute idiot, and got caught doing what he habitually does week in week out.
As for Neymar, and this agruement about a tap, or minimal contact, or no contact, or he was just running in his usual stride (haha),when Neymar is initially fouled, he slides quite a distance, 3 or 4 strides for Brown to get to him. He is sliding away from Brown in a different direction as he was going across Brown's path, and continues to slide facing the Celtic goal, not looking at Brown. Somehow Brown has turned to follow his slide, knows the whistle has gone, yet makes sure he runs into Naymar's path, and lifts his foot higher to make contact. Naymar did not know where he was, as he was facing the opposite direction, yet he immediately reacted to hold the part of his back that Brown appeared to kick going by the TV cameras. Strange he would know he had been kicked there if there was no contact!
Brown was an absolute disgrace and idiot for letting Celtic down, as he does not need to do that.
As for Lennon defending his actions and slagging off an opponent, he should be charged by UEFA.
As you mention in the first place, many off us were at Pittodrie on sunny day, when Neil Lennon did the same thing when there was no contact, and no attempt of contact. Feel like taking over the BBC and reminding Lennon of his own over reacrtions (cheating) back then. And why oh why do the interviewers afterwards never call it straight and go for the jugular. How can you justify defending your player after such a blatantly stupid action that probably cost you the chance of another massive result. What TV pictures did you watch that no one else has seen, as everyone else watching saw the kick! they have no guts to ask the questions
