It seems like déjà vu for Chelsea.
A big-money, high-profile striking flop has just left, with Timo Werner the latest in a long line of big-money, high-profile striking flops to move to Stamford Bridge amid much fanfare - and then struggle.
Werner won't even be the only striker to leave this window, with Romelu Lukaku farmed out to Inter Milan in June, a year after becoming the club's record signing.
Fernando Torres and Ballon d'Or winner Andriy Shevchenko also failed to live up to expectations, while Blues fans may remember the likes of Adrian Mutu and Mateja Kezman.
