Carlo Ancelotti has highlighted Aston Villa as a side with the potential to break up the Premier League's established big four. Martin O'Neill's Villa side leapfrogged above Arsenal into third place with victory over Sunderland on Tuesday night.
Chelsea remain top of the Barclays Premier League but only on goal difference over Manchester United who beat Wolves 3-0.
"Aston Villa are a very dangerous team," said Ancelotti. "They won against Chelsea and Manchester United. I think Martin O'Neill is doing a fantastic job with this team.
"Maybe we have to pay attention to them because nobody spoke about Aston Villa in the top four but now we have to pay attention to this team. I think Arsenal have to pay attention to them."
