West Ham United boss Sam Allardyce hopes to make early signings this summer.
Allardyce says their market plans are well underway.
He told whufc.com: "The planning has started, but it's about affordability for us. On the money side of it, there is some there but it's not fortunes. We've got to improve the team that we've got, which has played to its maximum.
"A lot of the team that we've got were free transfers and we've got to go from that to getting better players. We've got to go into the market for them and increase the overall salary and wage budget and transfer fees because we've got to try and get better.
"As we all know, that is a very difficult job to do today, to pick players to come in and be good enough to play in the Premier League.
"We've got to go all out and that's why I'm hoping that pre-season, aside from just players in and players out, is all sorted by the weekend of 26 and 27 May."
