Newcastle were lucky not to concede a penalty against Brentford in a decision that left Arsenal legend Perry Groves baffled.Dango Ouattara went down inside the box for the Bees following a challenge from Dan Burn, with almost an hour played.Ouattara could not believe he was booked for simulationGettyThe forward was shown a yellow card by referee Stuart Attwell for simulation.VAR then reviewed the incident and stuck with Attwell’s decision of no penalty, despite replays showing contact from Burn.The Premier League Match Centre said; “The referee’s call of no penalty and yellow card to Ouattara for simulation was checked and confirmed by VAR – with the challenge from Burn on Ouattara deemed to be minimal contact.”However, speaking on commentary for talkSPORT, former Arsenal man Groves was shocked by the decision from VAR.“That’s incredible. Paul Tierney, who’s the VAR… Ouattara has done his foot over with his left foot, gone on the outside of Dan Burn. “Dan Burn, with his left foot, has caught the top of Ouattara’s boot. Ouattara’s exaggerated it, he’s like he’s in Platoon, when you come out of an airplane and you’ve got a parachute.“He’s exaggerated it, but 100 per cent there is contact there. So, you can’t book Ouattara for diving because he’s actually been fouled. “I cannot believe that Paul Tierney hasn’t got involved in that, that’s ridiculous.”Olly Clink added: “He jumps, Ouattara, with his left leg.“The contact is on the right boot but like you say, if there has been contact inside the box, I think Dan Burn is very lucky there.”View Tweet: https://t.co/mrvgjyi17JOuattara fell in dramatic fashion, but Groves insisted there was contactGettyHowever, Sam Matterface appeared to side with Attwell and VAR, with he and Groves having a back and forth over the decision.Matterface: “Perry, not all contact means a penalty but the referee’s on-field decision is that Dango Ouattara dived.“He gave him a yellow card for simulation and no penalty. There is a tiny bit of contact. There is contact but the exaggeration the jump into the air does not come about because of that contact.“There’s no way that the level of contact that Dan Burn inflicted on Dango Ouattara makes him jump up in the air and kick his heels backwards does it?”Groves: “No it doesn’t Sam right but there is contact.”Matterface: “Therefore it’s not a clear and obvious error is it?”Groves: “No, it is, because obviously the referee thought there was no contact and you can tell that Dan Burn’s foot goes on to Dango Ouattara’s. He’s exaggerated.GettyBurn did later get sent off for a second bookable offence which did lead to a penalty[/caption]“I’m not saying he hasn’t but with an angle that we saw it’s Dan Burn’s left foot on Ouattara’s right boot and it’s on the top of his foot. So for Ouattara to get booked. I’m with you Sam, right, I hate simulation.”Matterface: “Not a penalty that I’m sorry. It’s not a penalty for this reason in my opinion.!Groves: “There’s contact. is there not contact Sam?”Matterface: “Yeah but not every contact is going to generate.”Groves: “So, is that not a foul? You don’t think that’s a foul?Matterface: “If you go back to the early part of the season there was a briefing from the Premier League in which they said that they don’t want soft penalties being given.“I think the referee has made the call thinking it’s simulation and he has been told by the VAR that there is no clear evidence to overturn that.“Even if he says there was no contact right I don’t think there’s enough contact there for Dango Ouattara to jump up do a triple pike dive into the swimming pool and then go head over heels on the floor.”Burn was later given his marching orders for a second yellow cardGettyAlex Crook: “Sorry and I’ll tell you what Perry he’s failed the pint test. If I’m in a club and I’m holding a pint I’m not I’m not going down.Groves: “I will guarantee you that the rest of the season right the rest of the season there’ll be penalties. we’re giving for less contact than that 100 per cent. It’s contact.Matterface: “So if the referee gives you on-field, that’s not going to be overturned because there was contact?”Groves: “Am I going mad here, Sam? You don’t think that’s a foul? That’s not a foul.“So when the ball goes on the outside of the defender and he goes to go past him and the defender put his foot on the top of the foot.So that’s not a foul? You’re telling me that’s not a foul?”Matterface: “It’s not that. I don’t think it’s a foul. I don’t think there’s enough in it to overturn it. Well is it a clear and obvious error Perry?What a high bar for intervention.Thiago completed the turnaround for Brentford in the 78th minuteGettyGroves: “No, it is a clear and obvious error because Stuart Attwell didn’t think there was any contact at all. Because you don’t know that.”Matterface: “You don’t know that because he hasn’t said that. He hasn’t said he didn’t think there was no contact.“What he thought was that the player Dango Ouattara exaggerated whatever the contact was and simulated. “That’s why he gave him a yellow card. He gave him a yellow card for simulation. He definitely gave him a card for simulation.”Groves: “Yes, because he thinks there’s no contact. That’s why. Well, you don’t know that. So that’s what VAR is there for, Sam. It’s okay to say to him, ‘Come and have a look.’Matterface: “Well they obviously had a conversation about it and decided that it was the right decision.Thiago added his second in stoppage time to win all three points for BrentfordGettyGroves: “Right, okay, if they’re going to carry that on for the whole season, right, Sam, I’m with it, right. I’ll guarantee you.“No, they won’t. I’ll guarantee they won’t. There will be penalties given for less than that this season, 100 per cent.”Harvey Barnes gave Newcastle a first half lead before Kevin Schade equalised for Brentford shortly before the controversial moment.Fortunately for the hosts, Burn was sent off for a second yellow card and Igor Thiago netted from the spot to put them ahead.Thiago scored a second in stoppage time as Brentford came from behind to seal a huge win in west London.
