#2 Nacho Monreal
I believe he is one of the most under-rated impressive players in the EPL. Arsenal must be counting their blessings having welcomed him to the club in 2013.
He hardly ever puts a foot wrong in his games and reads the game as well as his German team-mate Mesut Ozil. Lately, he showed his capability of running away from his markers and making dashes into the penalty box to score.
Monreal is also better than his fellow Spaniard playing in the right-back position, in terms of attacking and defending. Although he does not have Bellerin's pace, his crosses into the box are more accurate and he is by far, the most consistent player that Arsenal has.
In addition to being consistent, fans have nothing to complain when he plays. Just like all other players who have impressed, Monreal is Arsenal's Mr Reliable. There is no doubt in terms of his level of concentration and commitment.
Turning 32 years old this year, Arsenal may be Monreal's last club before he retires. His age does not seem to bother him much. When Sead Kolasinac has been brought into the team as a possible replacement for a spot as a left back, Monreal has dealt with things calmly and showed that experience comes before age.
