The Hammers have been planning for the future recently with James Tomkins, Mark Noble and Winston Reid all being handed new deals, and it seems that Collins and Sakho could also be in line to land contract extensions.
The pair are players who Sam Allardyce may feel still have an important role to play for the side and they could be crucial for their progression in the coming years.
West Ham have made no secret of their desire to break into the top-four and keeping their key players will be pivotal if they are to achieve their ambitious targets.
Sakho certainly falls into that category as the striker has had a brilliant debut season in English football.
The Frenchman arrived this summer as a relatively unknown quantity, but his pace and power has been a real weapon for the Hammers, with his total of 11 goals in 22 games hugely impressive.
Collins, meanwhile, is likely to continue to be back-up to West Ham's first-choice centre-back pairing of Tomkins and Reid, but Allardyce apparently feels he is reliable enough to warrant a new deal.
The Welsh international is 31, but he rarely lets the Hammers down when required to play and tying him down on a longer term deal would reduce West Ham's need to spend big on defensive recruits this summer.
