Egil Olsen
Player Valuation: £8m
Allan was on his way down, and in and out of a Napoli team that was struggling. He also struggled with injuries. He was by far the best under Sarri, and then as a box-to-box player who mainly protected Jorginho. The strategy of bringing in Allan and JR was madness, which only had a short-term perspective, which turned out to be very wrong. A club like Everton must bring in younger and hungry players who have not peaked, and who have the mental and physical profile to play in the world's most demanding league.
