Been disappointed with almost all the new signings so far tbh but the most disappointed in so far are probably Klaassen, Siggurdsson, Sandro and Martina.
Klaassen - looks like he is going to be an expensive flop.
Siggy - Way overpriced and just looks to be an average player. Might see a better side of him if the manager actually plays him in his best position.
Sandro - Great price but has done nothing but run round like a headless chicken but getting nowhere so far. Might come good when he gets used to the prem.
Martina - It was my understanding initially that he was brought in just as a backup for emergencies. Not good enough to be playing in the first team. His crosses are like Rugby kicks and he ends up mostly out of position and giving very little help to the position he is actually meant to be playing in.
Should also put in here Ronald Koeman as this season and the back end of last season he has been dire and doesn't seem to have a clue what he is doing. Everyone out of position, no regular starting 11, no plan, unable to install confidence in his team. Doesn't even seem that interested in Everton tbh.
The ones i have been the most impressed with so far are Pickford and Vlasic. Both look high quality signings.
