Austin has experience of England’s top flight from his time with QPR, where he scored 18 goals despite the London club’s relegation.
After sealing his move to St Mary’s, the 26 year-old is now keen to make an impression in the Premier League again and show he can reach the levels of 2014/15.
“I think it’s important as a centre forward to be established in any league you play, and to play in the Premier League is massive,” Austin told youtube.com/southamptonfc
“I had one season and then went back to the Championship, but now it’s important for me to establish myself in the Premier League.
“I got 18 goals during my first season and I just want to push on from that now.”
Asked whether there was any pressure on himself to prove his Premier League quality again, the former Swindon Town man added: “I think I proved myself the first time round.
“People always ask if a player can make the grade. I feel like I’ve set my standard now with that year at QPR.
“Now I just need to bring that to Southampton and take it to the next level.
“I think any professional would [thrive under the pressure], because they know what they’ve reached before and they want to get back to those heights.
“I don’t really set any targets. I just try to score as many times as I can every time I step across the white line.”
