For me, on the attacking front, Moreno's main flaw is that he totally avoids using his right foot. There have been many times over the season when he'd probably have been able to make a faster pass, or used his pace, switched directions and cut inside an opponent with one move if he would just use his right foot. At the very least, he'd at least not have slowed things down by waiting for the ball to sit nicely on his left foot before pressing ahead. I'm more frustrated by this than his inconsistent final product or his attacking instincts leaving him out of position (because Sakho is boss in sweeping up behind him, but yeah Moreno should improve on that). I'm not expecting absolutely two-footed beauty here, but geez, he could really use some improvement there.
Still, I'm happier with Moreno than Enrique or - HA! - Cissokho - HA! - though, so well, that's a good start. Flanagan returning to fitness (whenever) should add a bit more competition and also give us a defender who will be more solid at the back.
