Jonas Hofmann – £12m
The German winger would be an unfashionable signing but both the German and English press have been linking him with a move to Stamford Bridge over the past few months.
Hofmann is now 28 but he has recently broken into the German national team squad, and his flexibility is likely one of the main reasons why manager Thomas Tuchel is a big fan. He can play as a wingback, central midfielder or as a forward, making him an excellent utility player.
