Southampton have rejected a "substantial bid" from Liverpool for Croatian defender Dejan Lovren, sources have told ESPN FC.
Reports suggest the fee offered by the Anfield club is around 18 million pounds, but new Saints boss Ronald Koeman is eager to hang onto the centre-back after seeing three stars leave in recent weeks.
Lovren has reportedly made it clear to Southampton officials that he is keen to follow Lambert and Lallana to Liverpool, but the south coast club insist they are not prepared to sell any more key players until they have replacements lined up.
The Daily Mail has reported that Lovren, 24, is not expected to be at preseason training.
Meanwhile, Koeman has been promised the bulk of the cash from player sales to reshape the squad he inherited from Mauricio Pochettino.
