Karl Robinson has blasted referee Tim Robinson after Charlton’s 2-1 Carabao Cup win over Exeter on Tuesday evening.

The Addicks came from behind to progress to the second-round thanks to goals from Billy Clarke and Regan Charles-Cook.

But they did it in difficult circumstances after Andrew Crofts was shown a straight red card for a tackle in the 82nd minute.

It was the second time in as many games that Charlton have been down to 10 men. Lee Novak was given his marching orders for a two-footed challenge in the Addicks’ opening day win against Bristol Rovers.

Robinson said: “The referee was poor.

“The tackle on Saturday wasn’t a sending off and this one was disgusting. The assistant, who was stood next to me, gave it. Crofty went to ground, the lad has seen him, turned his left leg and backed into him. How is that a red card?

“I tell my players to play the right way and it looks like a lack of discipline on me. It’s good old-fashioned tackling. I didn’t even think it was a booking.

“Going down to 10 men every week is a new tactic. Maybe it will catch on!”

Meanwhile, Robinson was impressed with the youngsters who played in Devon.

The Liverpudlian made 11 changes to the side that won on Saturday – and started the Exeter game with seven academy graduates.

Young duo Anfernee Dijksteel and Reeco Hackett-Fairchild made their senior debuts for the club.

Robinson added: “The players were very, very good. Their attitude was exceptional and, again, our shape was very good.

“But the only disappointing thing was for me was that I thought we should have won the game by three or four in the first-half. We missed too many chances.

“From Dillon [Phillips], to Ezri [Konsa], to Anfernee, Joe [Aribo], Cookie [Charles-Cook], Karlan [Ahearne-Grant] and brining on Reeco at the end, it shows that Steve Avory is the best at what he does in the country.

“The game against a very good League Two side in front of a very hostile crowd at times, is a tremendous learning curve for all those young players and they’ve come through it with flying colours.”
