I think signing that kind of players is almost the worst thing we could do. They are decent, but not more and they are at their peak. They will cost a lot more than continental players and there is very little reason to think that we could sell them on for more than we pay (OK maybe Ings since he is a free transfer).
What little money we do have needs to go to players like Sanchez, Vlaar, Okore or Benteke. Known quantities that are not playing in England.
