Paul Scharner admits West Brom have exceeded expectations this season but insists they must retain all their squad during the January transfer window.
The Baggies moved back into the top half of the Barclays Premier League via Sunday's 3-1 home win over Newcastle - Chris Hughton's last match in charge of United.
But midfielder Chris Brunt has been the subject of speculation linking him with a move to Liverpool.
With head coach Roberto Di Matteo admitting he will be unable to make major additions next month, Scharner knows it is vital the current players all remain at the Hawthorns.
Scharner said: "It's true we have exceeded expectations but I am very happy that we surprised everybody.
"Hopefully we can continue what we are doing.
"Hopefully we won't stop when we reach our target (of staying up) and we will keep on going until the end of the season.
"It looks like we can stay up. I never got relegated with Wigan and that's why I came to West Bromwich, to help them survive.
"That's the main target and we're on course at the moment.
"But, if we want to reach our targets, it is important that we all stay together until the end of the season."
