7. David Luiz – Chelsea
After Chelsea announced the signing of Kurt Zouma, who will arrive at Stamford Bridge in the summer, that should have been David Luiz's cue to force a deadline-day move to Barcelona.
The Catalan giants are long-term admirers of the Brazil international, who couldn't be blamed if he fancied the idea of teaming up with Neymar and co. at the Camp Nou.
However, a big-money move could, you suspect, still go through in the summer.
