Arsenal manager Arsene Wenger has insisted that his team are in "fantastic shape".
The Gunners are currently 10th in the Premier League with 21 points from 15 matches, 15 points behind leaders Manchester United, and lost 2-0 to Swansea City at home on Saturday.
"This club are in fantastic shape," the Frenchman is quoted as saying by the Daily Mail.
"We have a good team, we have a strong structure that we have built over the years, we are in a strong financial situation and we are mentally strong.
"I can understand that not everybody is pleased about that, but that is a fact. That's why we have to continue to behave like we do."
Wenger also claimed that it is "fashionable" to criticise Arsenal.
"At the moment it is fashionable to be against Arsenal," said the Frenchman. "So, every single word you say, people turn it against you. It doesn't stop me saying what I truly believe in.
"I felt we lacked a bit of freshness [against Swansea] but it was not deep fatigue. People don't understand tiredness very well in England. They think you can only be tired at the end of the season.
"It's a lack of freshness, which you recover with one, two or three days' rest. It's not the only explanation for our defeat. We were a bit naive on the day. Superficial analysis thinks to turn it against you when it suits you."
Arsenal will take on Olympiakos in Greece in the Champions League on Tuesday.
