"Unfortunately, the penalty killed off the possibility of us coming back to get a draw and I was very disappointed with it. Having said that, Toure was onside in the first-half,'' he said.
"It's all about getting less negativity around the club. Over the years, Villa have fallen behind the top three or four clubs so there is a great deal of frustration.
"Getting a result at Highbury could have achieved that but, although we matched them for a long time, they are a special side with some exceptionally gifted players.
"I feel we are getting that belief back but Arsenal can score almost when they want to and against anyone. When they play how they can, then they're a level above the rest of us.''
