And reports claim that Southampton are at the front of the queue for the £8m-rated star, who is keen to move on next month.
Austin is believed to be reluctant to join a side battling against relegation, which makes the Saints an appealing option given that they’re outsiders to qualify for Europe for the 2016/17 campaign.
A move for the 26-year-old also appears to make sense for Koeman, who was forced to use Shane Long as his main centre-forward in the absence of Graziano Pelle in the loss at Manchester City on Saturday.
