The Gunners will face Villarreal in the first leg of their quarter-final tie on Tuesday.
“I really think it’s a 50-50 match,” said Wenger. “We are super-outsiders to win the Champions League because when you look at the bookmakers, we are not in there.
“The favourites are Liverpool, Manchester United and Barcelona. It puts a little less pressure on you but, once you are on the pitch, it doesn’t change too much.”
