Ryan Nelsen believes West Ham have issued a statement of intent by tying Winston Reid to a new deal.
Fulham defender Jack Grimmer has signed a new two-year contract to keep him at Craven Cottage until the summer of 2017.
Barcelona and big-spending Monaco have both been credited with an interest in Kompany as they look to bolster their defensive options.
However, Kompany has moved to play down the rumours and insists he is staying at City as he has "unfinished business" at the Etihad Stadium.
"Speculations and questions about next season.. I'm not going anywhere," Kompany said on Twitter.
"I love playing for City and I've still got some unfinished business."
