Newcastle United boss Alan Pardew says there can't be instant change at the Magpies.
Pardew says finances mean it must be a gradual transition.
He told BBC Radio Newcastle: "As it stands financially at the moment, we can't compete with those top teams in terms of trading players.
"But of course we can compete on the football pitch, so what we have tried to do is bring in players that we feel have an improvement in them and a desire to play for Newcastle, and that's why we targeted the players that we have.
"Now the most important thing to keep those players is to put success in front of them.
"When you are building a new side, it needs to have progression, and that's something we are going to need this season, we are going to need to see a progression in our form, in our consistency and get as close as we can to those top teams.
"If we see that, I think we an keep them another year, and then when we go into that second or third year, then you really, really need to be very, very close because then they are going to start looking, as Jose is now, for those trophies, and I think we can do that.
"The likes of [Cheick] Tiote, Cabaye and people like that, we are going to have to have success on the pitch to keep them, 100%."
