Karl Robinson was left frustrated with Charlton's 1-1 draw against Oxford United on Tuesday evening.

The Addicks took the lead through Tariqe Fosu’s 18th-minute strike and dominated the first-half. But they were pegged back 10 minutes before the break by a Christian Ribeiro volley.

Charlton then passed up more opportunities in the second-half and were forced to take a point back to the Valley. It is an all too familiar scenario for the Addicks, whose failure to take their chances has cost them already this season.

And while Robinson says his team’s performance was one of the best under his reign, he was annoyed with a draw.

He said: “I’m frustrated. I’m absolutely frustrated.

“We cleared one off the line in the first-half. It was probably one of the best games I’ve watched all season - on the eye - that was as pleasing as it gets.

“Oxford have an outstanding team at this level. I thought we were the better team, they might say different. We had six or seven really good chances - chances we normally take. 

“We looked as fluid and as classy as I’ve seen us this season against one of the best teams - away from home.

“So, if I could swear I could. I’ve got so much stuff I want to get out because it’s frustrating for me.”

Naby Sarr impressed once again after filling in for Ezri Konsa, while Ben Reeves made his first league start for Charlton.

Robinson added: “I’m proud of my players, Naby came in for Ez, it was a tactical switch that I thought worked.

“Reevesy playing on the right, he’s a 10, he still needs to get his fitness up. He kept the ball for us. Karlan could've scored at the end so we’re really pleased with our team performance today.

“Ez was one of our best players on Saturday. He went away with England, he had a little tightness in his groin playing at Fleetwood and England flagged it up to us.

“He came back played 90 minutes on the Tuesday, played 90 minutes on Saturday against Doncaster. To go again tonight was a risk which wasn't worth taking.

“And off the back of Naby’s performance at Fleetwood, I think everyone’s seen he’s a different man. He’s a completely different man. People have given him a chance and he’s performed really well.”
