Chelsea forward Hakim Ziyech has come under heavy criticism from supporters following a poor performance in Tuesday's shock loss to Dinamo Zagreb.
Blues fans have taken to Twitter to vent their fury at the Moroccan international's performance, after he was introduced at half-time, replacing Cesar Azpilicueta.
But he was unable to make a positive impact as the west London side fell to a 1-0 defeat, as the 29-year-old was wasteful and largely ineffective for much of the second half.
Chelsea fans on Twitter were quick to slam his performance, claiming that it is one of the worst performances from a Blues player coming off the bench.
