#1 Eden Hazard
Not just in midfield, but in the FPL game in general, you can't look past Chelsea's star man this season. Hazard has been phenomenal thus far taking his fantasy appeal to even greater heights than even that of Salah due to the Belgian being priced significantly lower at £11.3.
Even though he missed the last game with an injury, Hazard would be expected to make a return against Crystal Palace next week, before facing Everton and Spurs. But really, he should be in your team in spite of the fixture or whichever team you opt to play.
The Belgian has only played 666 minutes so far but has gathered 75 points which include 4 double figure returns. He has 7 goals, 3 assists and also leads the table in bonus points, having gathered 13 of those so far.
On current form, there are other Chelsea players to look out for as well, such as Ross Barkley but if Hazard stays fit, I see no reason to be going for someone else.
