Ronald Koeman, Southampton manager has stated no player will be leaving the club despite the arrival of Austin.
The acquisition of the QPR striker has prompted talk of Koeman selling Shane Long to Liverpool or Mane to United.
Koeman however has stated there will be no player leaving the club.
“We brought one player in and nobody will go out,” the former Barcelona defender told reporters. “I keep that until January 31. You know my answer but maybe I have to repeat it 80 times more.”
Koeman confirmed Austin could make his debut on Saturday against Manchester United and hopes he can emulate Jose Fonte and Graziano Pelle in becoming a late-blooming international player while at St Mary’s.
“He’s very hungry, he wants to play at the highest level,” Koeman said. “He wants to develop, he’s still only 26, and he’d like to get back in the national team.
“People come to Southampton knowing they can get involved in national teams – Jose Fonte and Graziano Pelle got theirs aged 29. It’s interesting for players to come to Southampton, they know they will improve and develop.
“We signed him because he has played and scored in the Premier League. He’s at a fantastic age to make a new start and he gives us competition at the front of our team.
“I was a little worried because Charlie had a hamstring injury before we signed him, but he had all the medical tests and took part in all the training sessions this week.
“We had to test him to know he is available and on his fitness tests he is as good as the rest of the players. I wasn’t expecting it so quickly but it’s nice to be surprised. He will be in the squad this weekend.”
