I remember Derek Mayer coming from Everton played in the 57/58 runners up team.
That is a bit before my time as a supporter though obviously he did make a major contribution. Most of the other players mentioned after my initial post - thanks for the replies everybody - didn't make much of an impression at the time as I recall though did we actually get McGeady from Everton in which case he is an exception. The player we signed from Everton I recall most vividly for less than the best reasons is Ray Veall. I have mentioned him here before - he was a left winger who literally could not run in a straight line when he had the ball. Instead he constantly zigzagged in and out as he moved forward so that if you had put some white paint on the soles of his boots he would have left a saw edge line all the way along the inside of the actual touchline - as I recall he lasted about half a season. Heaven knows how this board would react if we signed someone like that today.
