Debate: Who's been the best signing of the transfer window so far?

Britain may be sweating its way though a heat wave but at least we have the breeze generated by the fluttering of Premier League chairmens chequebooks to keep us cool.

Yes, as we approach the mid-way point of the summer transfer window, the big money moves are coming thick and fast.

Ronaldo, Barry and Lampard might still be kicking their heels and speed-dialling their agents, but we have seen the likes of Robbie Keane, Jose Bosingwa, Jo, Luka Modric, Samir Nasri, Peter Crouch, Joan Elmander and Deco all make high-profile switches.

And with deals for David Bentley and Andy Johnson due to complete in the next day or so, theres plenty of big transfers still to come.

So, who do you think has been the best buy of the summer so far, and why?
