Koeman warns Southampton must buy in January

Southampton boss Ronald Koeman is eager to buy in January.

Koeman's three-year contract expires at the end of next season and owner Katharina Liebherr is desperate to tie him to a new deal.

But he said: "My future is depending on what the club can do. We will speak about it.

"It is all about ambition. I hate to stay in a situation where there is no ambition.

"Until today the club is showing that ambition and if we continue like that the possibility is to grow and to spend money.

"Of course that will have a big influence in my decision to stay or not to stay.

"The club is doing everything we can but that is about next season, to bring better players in and have more competition and to grow as a team."
