The Gunners are without a league win in 2013 and are currently sixth in the table, seven points behind fourth-placed Tottenham.
"They care as much, if not more.
"People have the right to criticise when the games don't go as well as you want but I can show you games of the players you spoke about. I can tell you some bad starts (from them) as well. I can show you some goals where you can see where they were not completely untouchable. That happened to them as well."
The Frenchman admitted that morale was low amongst his players but he has backed them to bounce back.
"What is worrying is just that we do not win the big games. The position we are in now is a bit backs to the wall," said Wenger. "We have to respond. I'm confident that we will but the team was very down after the Chelsea game.
"Tomorrow is a very important game for us. We have to transform the potential we have shown in the (last) two games into points and tomorrow is a good opportunity to do it."
"The difference in points mathematically is not dramatic, but the consistency of our performances within games is what is worrying," Wenger added.
"When you see how we played in the first half (at Chelsea), and how we played in the second half it is difficult to believe that we are the same team. That is more worrying for me."
