Without Sigurdsson in the side Everton's two playmakers have basically been Baines & Coleman.
Which worked against Stoke, but failed in every other match against City/Liverpool/Swansea.
Rooney & Davies simply aren't adequate, thus putting more pressure on our fullbacks to deliver in attack.
Bolasie & Walcott possess zero playmaking ability and aren't nearly as calm & composed as Baines/Coleman.
Our midfielders barring Sigurdsson lose the ball too frequently, and rarely pass forward. So our 'true' at the moment playmakers are our fullbacks.
Next season I'd like to see our XI like this:
With Gylfi centrally & Lookman/Walcott on the wings and two good DM's we'd get the best out of our fullbacks.
Our defense has been solid since they both returned, our biggest problem has been our attack by far.
