Manchester City this weekend.
The Villians are currently three points above the relegation zone having won just two of their opening 11 Premier League fixtures so far this season.
But the 21-year-old, who scored both of Villa’s goals in their 3-2 loss to Manchester United on Saturday, believes there is enough confidence around the squad to come away from the Etihad Stadium with a positive result.
He told Sky Sports: “We don’t have fear, and we shouldn’t have. The last weeks we have got confidence because we have won a couple of games.
“You have seen the way we played against Manchester United. At the moment we think we can take on anyone and at Manchester City we will be the same.
“We went there in the cup and got a win. It is going to be a really hard game but we will go there with a lot of confidence.
“I am sure that if we play like that we have got a chance of getting something.”
Weimann also admitted he is happy playing in the wide role manager Paul Lambert has asked him to play, despite being a natural striker.
“Obviously, I would say my best position is up front, but I really like this role because what the gaffer wants me to do is come inside and make runs in behind Christian Benteke,” he told Aston Villa’s official website.
“It does sometimes let me sneak in unnoticed – that’s what happened for my second goal against Manchester United. I’m getting chances in this position so I’m happy to play there if the manager keeps picking me.”
