Celtic manager Brendan Rodgers likened modern football to a “computer game” after claiming Daizen Maeda was sent off following a needless VAR intervention in his side’s 6-0 defeat by Atletico Madrid.

Maeda saw a yellow card upgraded to red following a VAR review midway through the first half at the Estadio Metropolitano, but Rodgers felt referee made the right call initially.

The Japanese attacker dangled a leg in a 50-50 challenge with Mario Hermoso, who hurt himself as he followed through.

Celtic were already trailing to a deflected strike from Antoine Griezmann and Atletico took full advantage of the numerical superiority. Griezmann and Alvaro Morata both struck doubles, while Samuel Lino and Saul Niguez also scored as Atletico hit a string of spectacular second-half goals.

Rodgers said: “I think the red card is a big turning point. We started well, started with confidence, got into some really good areas. We then get a man sent off early, which was a huge disappointment because I didn’t feel it was a red card.

“When you watch the re-run, both players kick each other’s feet. The referee saw that in game time and then he is asked to look at it.

“The first image he sees is not representative of the actual challenge. You plant a seed when the first image he sees is Daizen Maeda’s foot up, but that wasn’t the challenge and it’s a really, really soft red card.

“For a team coming here with 11 against 11, you would need to be at your real max to get something out the game and losing a man early, it becomes a real challenge and we tire and they scored some fantastic goals.”

Rodgers was angered by the reaction of the Atletico bench after the Maeda challenge, with boss Diego Simeone and six or seven colleagues racing into the technical area to remonstrate.

He said: “They will play the game, they are obviously trying to get our player sent off.

“Listen, it’s still up to the ref. You come away in Europe and a place like this where it’s an emotional stadium, everyone will add pressure.

“The ref saw it in game time and didn’t deem it worthy of anything so serious, but it just feels like a computer game now, football. So many visits to the screen, so many influences in the game.

“As time has gone on you see the influence of VAR and the difficulties referees have. There’s a lot of judgements going on away from the field.

“It’s not so much the technology, but how it is implemented. It’s not something I enjoy.

“When it first came out I was very much wanting to support it and hoped it would improve the game, because I think everyone thought the utopia of VAR would mean we would lose all these bad decisions.

“But you could argue there’s even more now. There’s a good percentage where it just doesn’t feel right in the game.”

Rodgers maintained a 4-3-2 formation after the red card, with Oh Hyeon-gyu coming on at half-time.

“You have seen my teams enough back home,” he said. “Whenever we lose a man it’s having that structure.

“Listen, you can have any structure you want, it can be very, very difficult against that level of opponent. It just didn’t work for us so we have to take our medicine.”

Celtic remain bottom of Group E but are still not eliminated from the Champions League, although they will need to beat both Lazio and Feyenoord and hope Atletico do them some favours to stay in Europe beyond Christmas.

Rodgers said: “We knew we had to take something from this game, but with Lazio winning as well, our objective with two games to go is to get points and see if we can improve on last season’s points total.”

Daizen Maeda was sent off as Celtic suffered a thumping 6-0 defeat against Atletico Madrid to leave them adrift in their Champions League group.

Celtic were already trailing to Antoine Griezmann’s deflected goal when Maeda saw a yellow card upgraded to a red following a VAR review midway through the first half at the Estadio Metropolitano.

Alvaro Morata and Griezmann both netted doubles and Samuel Lino and Saul Niguez scored as Atletico capitalised on their numerical advantage in devastating fashion with a string of spectacular second-half goals.

The damage was done when Maeda left a foot dangling as he went in for a 50-50 challenge with Mario Hermoso, who rolled around on the floor after being caught on the shin as he followed through.

Atletico boss Diego Simeone and six or seven of his backroom staff raced off the bench after the incident, sparking an angry reaction from Celtic manager Brendan Rodgers when the referee was called to his monitor.

Rodgers was booked for dissent as Simeone dragged one of his colleagues back from confronting the Celtic boss.

Celtic are now five points adrift of third-placed Feyenoord and, although not eliminated, they will need to beat Lazio and the Dutch side in their final two games while relying on favours from Atletico to have any hope of extending their European run beyond Christmas.

They will travel to Rome for the November 28 game with Lazio without Maeda and fellow winger Luis Palma, who picked up his third yellow card of the campaign when he was booked for dissent.

Rodgers picked the same team that played the bulk of the 2-2 draw with Atletico two weeks ago. That meant Paulo Bernardo came in for David Turnbull, who had scored in each of Celtic’s last two league games.

Griezmann started in midfield and opened the scoring in the sixth minute after Celtic twice put themselves under pressure.

Joe Hart sliced a punch clear under no pressure following a corner and Callum McGregor headed a poor clearance straight to Griezmann.

The Frenchman shot from 20 yards and a deflection off Cameron Carter-Vickers took the ball out of Hart’s reach and into the bottom corner.

Palma forced a save with what would prove Celtic’s only effort on goal as they tried to respond and McGregor soon saved his side by blocking from Rodrigo Riquelme following a counter-attack.

The red card soon followed and, although Atletico goalkeeper Jan Oblak saved brilliantly from Morata’s sliced clearance, the rest of the game was an exercise in defending for Celtic.

Griezmann, twice, and Nahuel Molina threatened before the France international’s diagonal ball exposed Celtic in first-half stoppage time. Jose Maria Gimenez headed across goal for Morata to slide in and convert from close range.

The onslaught continued, even before the interval, when Hart saved from Angel Correa.

Rodgers brought on Oh Hyeon-gyu for Palma at half-time as he maintained his 4-3-2 formation throughout.

Griezmann continued to threaten on regular occasions and Gimenez headed off the bar before the Frenchman netted with a scissors kick on the hour mark after meeting Alistair Johnston’s headed clearance.

Substitute Lino took a step inside Johnston and curled in a brilliant fourth six minutes later.

Correa hit a post before Morata took a touch on the edge of the box and lashed a shot into the roof of the net in the 76th minute.

Celtic finished the game with a midfield of Turnbull, Odin Thiago Holm and Tomoki Iwata and they lost a scrappy goal in the 84th minute when Niguez finished from close range.

Their heaviest European defeat had come in Spain under Rodgers seven years ago and Atletico could not emulate that 7-0 victory amid further pressure.
