Pardew says West Ham must invest in their squad this summer.
Pardew said: "It's very important that the [West Ham] board is strong and that they invest, because you can't cut and cut and expect to get promoted.
"Newcastle took a very strong view on that. West Ham might not financially be able to do that, but they can't cut it to the bone.
"They have got to give the next manager a real chance. They are experienced people there and I think they will give the manager every chance, and I certainly hope they do so."
