I don't see the magic in 3-5-2. Clyne and Bertrand have no problems coming up and joining the attack, and our defense is just fine with only two CB's back. And we still can't score.
They just need to sort out the attacking movement with the players we have. Put Tadic back in the left or maybe in the center, and most of the problem goes away.
Elia and Mane are too similar. If one guy can get in behind the defense, that's enough. You don't need two players to run behind the defense, much less three. We aren't having problems on breakaways and counters, we're having problems creating even half-chances when the defense is set.
I disagree strongly that most of the problems go away simply by putting Tadic on the left/center. On the left he can provide crosses, sure, but there's no one to attack those crosses right now; Pelle isn't gambling (there's merit to having a player hanging out near the penalty spot, but when it's your striker and no one else is getting across the face of goal, it means a lot of nothing balls), Mane/Elia aren't really headers of the ball, no one else is getting into the box with much regularity. Playing him in the center may provide better ball movement, but only if there's someone on the end willing and capable of making good the chance.
That's where the problems are coming from in creating chances; there are simply too few players on the pitch at any given time with much inclination to turn a good ball into a good chance. Mane is one. Elia's not a natural finisher, never has been, and what finishing he brings tends to come as a result of getting behind defenses that are not set. Pelle's been off the boil for a long time. Tadic is shot-shy. Our central mids aren't snipers (Davis/JWP as the front man of the midfield trio have been particularly wasteful) and while our fullbacks are attacking threats, they can't be expected to bang in goals left and right. And the totality of it has looked so meek of late that I struggle to think that simply shifting one player is going to turn us into predators out there.
