 This allowed Seith the opportunity to compete in the European Cup which had been denied him by his acrimonious departure from Turf Moor and he featured prominently in the "Dark Blues" run to the semi-final, where they eventually lost to eventual winners A.C. Milan.Seith retired from playing in 1964, joining the Dundee coaching staff before moving to a similar role with Rangers; he was to resign from his Rangers post in protest at the sacking of manager Scot Symon in 1967.He earned his first opportunity as a manager when appointed to replace Jimmy Milne at Preston North End but left in 1970.
