Very much like Unai Emery at Arsenal, who managed to piss up a virtually secured Campions League position up the wall, Silva has bought himself very little leverage from his first season which puts him under much greater pressure - than say Roberto Martinez was under in his second season.
That 8th position, which was only secured thanks to a scorching run of home results towards the end of last season, is going to be very quickly forgotten about if we look like replicating our December to February form.
Silva really needs to settle on a team and system soon to accommodate the options he has. On the face of it, dropping someone like Sigurdsson who is one of our most reliable goal scorers might seem foolish but this ridiculous second striker role that Silva has him play is really hampering Gylfi's effectiveness and our team as a result. Surely trying a 4-3-3 won't hurt?
