SHEFFIELD, England -- Arsene Wenger expressed concern about injuries suffered by Alex Oxlade-Chamberlain and Theo Walcott but offered congratulations to Sheffield Wednesday for their 3-0 demolition of his Arsenal team in the Capital One Cup on Tueday.
Oxlade-Chamberlain, suffering a hamstring problem, was replaced at right wing after just four minutes by Theo Walcott, who only lasted 10 minutes himself before pulling up with a calf problem.
"The injuries are two muscular injuries and we have to make the scan and wait 48 hours to see how bad the damage is," said Wenger at his postmatch news conference.
"It was a bad night at the office for us because we lost the two players and after that we were not good enough."
Goals from Ross Wallace, Lucas Joao and Sam Hutchinson blew away an inexperienced Gunners' lineup at Hillsborough.
Wenger fielded 10 internationals in his starting XI but had made eight changes from Saturday's 2-1 victory over Everton, with trips to Swansea City and Bayern Munich coming up in the next week.
Wenger said: "I am concerned because we have a big game on Saturday, and the Champions League at Bayern coming up and we are short. To lose two players is damaging to us, and two offensive players."
Exiting the competition was still a disappointment despite it lightening Arsenal's schedule.
"Ideally, I would have loved to win tonight," said Wenger. "But it is true that with the squad we have now, we cannot deal with all the competitions.
"You have to congratulate Sheffield. They put a great performance in. They were very resolute, very dynamic, so they deserved their win tonight."
Wenger's attempt to rotate backfired and he admitted he did not dare risk another senior player.
"I have to manage the workload of the players at the moment," he said. "I still think I brought too many experienced players here because we lost two players, and once I lost two players I had Gabriel and [Nacho] Monreal on the bench. I didn't bring them on because I couldn't afford to lose any more players."
The Gunners were not able to cope with the dynamic nature of the Owls' display and boss Carlos Carvalhal, who has overseen a nine-game unbeaten run in all competitions, knew his side were too good on the night.
"I am very happy about the victory, I think we deserved it," he said. "Everything belongs to the players, they were fantastic, we put a plan together and they did it 100 percent.
"I am very happy about the players and for the club, it is an important victory for the club. It was a full stadium, with a new generation of fans. We deserved what we got.
"When you play against a club that beats Bayern Munich, they have a squad full of internationals, they are near the top of English football, there is a big gap.
"There is still a big gap. We know they are nine times better than us as a minimum, On the pitch we were better than Arsenal tonight, but we are not better than them."
