Why on earth are you guys not citing Sergi Roberto as THE flop !!!??
He was directly responsible for both their goals ..... he has to be the worst RB in the history of RBs ..
For the first he was the nearest player to the guy striking the ball and he was slow to close him down then tried a half hearted block , turning his back on the ball !!!! The second was even worse with non existent marking at the back post - he has no natural defensive instincts and doesn't even commit himself to the cause ...
