#1 Kepa Arrizabalaga (Chelsea)
Kepa Arrizabalaga has been the most high profile flop of the Premier League season so far and the Spanish goalkeeper has cost Chelsea several points this season. Of all the goalkeepers in the league to play over 1000 minutes, the world's most expensive goalkeeper ranks worst for save percentage, save percentage from shots inside the box and expected goals - a torrid record considering the amount of money the Blues paid to sign him.
Frank Lampard is reportedly looking to offload Arrizabalaga at the end of the season, a move that is set to go down as a statement considering the circumstances and the Spaniard only has himself to blame. Chelsea's defence is questionable, to say the least, and Arrizabalaga's problems have added to their woes at the back, as the young goalkeeper has single-handedly cost his side points.
When the season began, Arrizabalaga was tipped to have a big season and make a name for himself as one of the best players in his position and was even earmarked to displace David De Gea for Spain, but both have them have struggled for form and consistency this time around.
Arrizabalaga is running out of time to turn his fortunes around at Stamford Bridge and he needs to do so quickly or risk getting shipped off in the summer.
