Southampton manager Ronald Koeman has reiterated the club will not be selling anyone during the January transfer window following the arrival of Charlie Austin. Austin, 26, completed his move to St Mary's ahead of Southampton's comprehensive 3-0 win over West Brom on Saturday 16 January.

Ahead of the striker's arrival, the Sun speculated Saints striker Shane Long has attracted the attention of Liverpool manager Jurgen Klopp. Sadio Mane meanwhile has already been subject of an offer from Manchester United, according to the Daily Mail, one swiftly turned down the south coast club. But while some have speculated the arrival of Austin may lead to one of the club's current forward options leaving, Koeman is adamant no one is for sale.

"He was our target for January," Koeman told BBC Sport. "The number of goals he's scored in the Premier League is amazing. We're looking forward to having him in the squad, and having more competition. That will be good.

"Will someone be sold? No. Nobody is for sale in January. At the end of the season, you don't know, but not now. We like to make the squad stronger, that means Charlie in, nobody out."

Austin, whose contract at QPR was to expire at the end of the 2015-16 season, signed a four-and-a-half year contract with Southampton ahead of kick off.

"I'm delighted to have got it over the line so soon into January. I can't wait to get started now," Austin, who scored 18 Premier League goals last season, told the club's official website.

"As soon as Southampton showed an interest that was the one club I wanted to go to. You see the progression from when I was playing against Southampton for Swindon. For me, it was important to come to a club that's on the up and that's what I've got here."
