I couldn't stand Stones and Rom but we got rid of them without adequate replacements. Then marginalising Barkley and Delefeou. Literally the four biggest talents we had.
Martina, Rooney and Keane were shonky signings.
Klaassen and Sandro ain't played in position at all.
Pickford looks good, but hardly an upgrade on Robles. But he is young and will get better. And needs a defense in front of him.
As for Gylfi. We paid overs, we had far greater problems then signing another CAM, and neglected CB, LB and a decent CF. He is a good player but lacks the zing and doesn't add near as much from open play as people thought he did.
Klaassen and Sandro need to play and be given a go in their actual position. But apparently that excuse only applies to players who have solididied themselves as fan favourites.
