#4 Hector Bellerin
During the transfer window in the summer, Hector Bellerin was being linked with a move to either of Barcelona or Manchester City and there was no reason to be surprised at such approaches since he was among the best young right backs in Europe at the time.
However, that assertion can no longer be made with as much conviction following the young Spaniard's shows for Arsenal in the 2017 season. This season Bellerin has been a liability for Arsenal on many occasions and some of the numbers clearly illustrate that point.
According to Squawka, he has made the highest number of defensive errors among all Arsenal defenders and one of those 3 errors has directly led to a goal. On the other hand, his much-lauded overlapping runs down the right have not amounted to much either and his crosses have been quite disappointing.
He has a pass accuracy of 85% and has also been able to claim only 1 assist all season. Hopefully, he will be able to reverse this sorry trend in the new year.
