Southampton boss Ronald Koeman has warned Victor Wanyama's admirers nobody will be leaving St Mary's next month.
Tottenham and Arsenal are both known suitors for the player.
"They can prepare whatever they like to prepare," he said. "Don't spend time trying to buy a player from Southampton because it's impossible.
"They talk about players from Southampton because we have some good players and there is always interest in players. And the ambition of players is about playing Champions League.
"We know what we like to do and how we like to do our business. That means in January nobody will leave Southampton."
