NEWCASTLE UNITED’S negotiating technique was slammed by Montpellier yesterday before they were warned to expect a fight if they want to land another attacking target, German striker Pierre-Michel Lasogga.

Hertha Berlin are understood to have told the 22-year-old that they would like to keep him unless meeting their £10m valuation is met.

Hamburg, where he spent last season on loan scoring 13 times in 20 appearances, are keen to have him on board again next season.

But Hertha are impressed with what he has done with Hamburg and director of sport Michael Preetz thinks Jos Luhukay’s squad will benefit from having him around again next season.

That has created a problem for Newcastle, with the player entering the final year of his contract theyt hoped he would be available for a lot less than his market price.

Hamburg have made a firm offer, but Preetz has not accepted defeat at this stage and met up with the player in midweek. He is expected to join pre-season training on June 30.

Newcastle are desperate to add extra options to Alan Pardew’s attacking ranks over the summer to fill the voids left by the exits of Loic Remy, Luuk De Jong and Shola Ameobi.

Despite the signing of young Spaniard Ayoze Perez, the Magpies’ only senior first team striker is Papiss Cisse, who is recovering from a serious knee injury.

Numerous forwards have been considered, including Leeds United’s Ross McCormack, who was the subject of a £5m offer from a team in the Championship in the last 48 hours.

And Newcastle remain in the hunt for France international Bafetimbi Gomis who is a free agent on July 1 when he officially leaves Lyon.

Another target is Gomis’ compatriot and Lyon team-mate Alexandre Lacazette. The 23-year-old would, however, cost more than £10m amid competition from Arsenal.

Newcastle have also been warned off Swansea’s Wilfried Bony. The Ivorian, on duty with his country at the World Cup, is on the look out for a Champions League switch and his agent suggested yesterday that around £20m could be required to clinch a deal.

Yesterday saw the latest twist in the Remy Cabella saga. Cabella, in Brazil with France, is one of Newcastle’s top targets this summer despite Montpellier’s insistence that he will not be sold for less than £12m.

But the French club’s outspoken president Louis Nicollin has directed another swipe at St James’ Park, suggesting he is sick of the recruitment tactics used by the Tyneside club.

Nicollin said: “Yes, the ‘great’ English club Newcastle has made us an offer of 8m euros from three weeks ago, which I refused. I do not think Newcastle is right for him and I also think they are taking us for idiots.

“They sold Yohan Cabaye to PSG, for I do not know millions, and they should not take us for fools.''
