Liverpool's fight to prise Dejan Lovren from Southampton has intensified after his manager demanded he returned to pre-season training.
The Reds have already had a £20m offer for the Croatian defender turned down this summer and the Saints are set to dig their heels in.
Lovren has made it clear he wants to join Liverpool and has handed in a transfer request but his new manager at St Mary's, Ronald Koeman, has told him he must come back to the club.
The 24-year-old is Brendan Rodgers' number one defensive target and hopes to reunite him with former team-mates Rickie Lambert and Adam Lallana at Anfield.
Lovren believes there was an agreement in place that if a club offered £20m for his services then Southampton would let him go.
But Saints are refusing to play ball and Koeman expects the centre-half to rejoin the rest of the squad this weekend.
"Dejan is a Southampton player, he has a contract and he must return," Koeman is reported to have said.
"This is a great club and we like to have all the players in the squad happy but he has to come back by Sunday.
"My feeling is he will be here at the start of the season."
Last week Lovren said that his "head is already at" Liverpool.
Wilfried Bony, meanwhile, has emerged of interest to the Reds but no approach has been made, contrary to reports.
The Swansea City striker is understood to be on a list of potential signings as Rodgers looks to fill the void being left by Luis Suarez.
Suarez is edging closer to a move to Barcelona after a deal between the Spanish giants and Liverpool was agreed. Barca have met the sell out clause of around £75m in the 27-year-old's contract and Suarez is expected in Spain early next week to complete his medical and finalise his transfer.
Should Liverpool want Bony as his replacement then reports say they will have to pay a £19m buy-out clause in his deal at the Liberty Stadium.
The Ivory Coast striker, who played at the World Cup, is not agitating for a move away from South Wales but has made no secret of his desire to play Champions League football.
