Sigurdsson is sound and one of the few we have who is fairly reliably EL standard.
I didnít particularly want him, but I have grown to quite like him. Absolutely guaranteed goals and assists in the prem - just needs ball magnets around him to actually get involved in the play.
Say what you want about rooney he did want the ball, sig not so much, which is why he couldnít make it at a higher level. You need to do both e.g hazard, coutinho, de bruyne etc.
