West Ham chairman Eggert Magnusson is confident Carlos Tevez and Javier Mascherano will not be leaving Upton Park in the January transfer window.
And the Hammers' new owner plans on holding talks with Kia Joorabchian's consortium with a view to striking an extended deal for the two Argentina internationals.
Joorabchian orchestrated their transfer to West Ham from Brazilian club Corinthians in August but retained a controlling stake in their careers.
And when Joorabchian lost out to Magnusson in his bid to take over West Ham, it seemed as if Tevez and Mascherano would be moved on.
But Magnusson told Sky Sports News today: 'I can more or less say that they will be staying with us until the summer so I'm looking forward to these players showing how good they are.
'There is also a FIFA regulation that says players cannot play for more than two clubs in one season.
'After that it is not up to us because we don't own the players.
'There is a consortium that owns the players. In the summer we have to talk to them because they can take them away to another club if they want to.'
Tevez and Mascherano have struggled to adapt to the rigours of the Barclays Premiership.
The disruption caused by their surprise arrival in August was blamed for West Ham's poor start to the season.
Tevez is yet to score while his compatriot, a mainstay of the Argentina World Cup midfield, has been kept out of the West Ham side by Hayden Mullins.
But there were clear indications in yesterday's defeat at Everton why both Magnusson and manager Alan Pardew want them both around for at least the remainder of this campaign.
Magnusson said: 'I think Tevez yesterday showed that he's a really good player.
'After everything has settled and the takeover is finally over I'm sure they will start to show us what kind of world class players they are.'
Joorabchian first became involved with Tevez and Mascherano when his former company Media Sports Investment bought them for Brazilian club Corinthians.
Joorabchian has left MSI but he retained an interest in the two internationals and last August offered them in a unique deal to West Ham.
West Ham retain their registrations but Joorabchian controls their careers.
At the time it appeared their arrival would pave the way for Joorabchian's consortium to buy West Ham.
