Though he failed to find the net, Simpson impressed Palace manager Fred Mavin who signed him the following summer.
[4] In the 1930–31 season, he achieved a Palace record, scoring six goals in a 7–2 win over Exeter City, in a Division Three South fixture.
[7][8] After two largely un-noteworthy seasons with West Ham, and still not fully recovered from his injury, he left in 1937, moving to Reading.
He would return to Selhurst Park in early 1938 with "The Royals", and score two of Reading's three goals, to beat "The Glaziers" 3–2.
[3] However, though he did not make it into Palace's Centenary XI (possibly because the majority of the voters were more accustomed to the talents of later players, Ian Wright and Andrew Johnson, who played in the top division, rather than a vintage great, such as Simpson), the record books of Crystal Palace F.C., continue to show Simpson's achievements.
