Chelsea chief Peter Kenyon has hinted at big-money signings this summer.
Jose Bosingwa has already been signed from Porto for £16m as a replacement for Juliano Belletti at right back, and is the first of three, possibly four, stellar signings.
Kenyon said: "We've bought Bosingwa and that strengthens a position which has been an issue for some time. It was good to get that done but I think it's two (more) rather than 20. We are pretty confident about the players we want to keep. That has always been our position."
