The 1965/66 season saw United return to the top flight after a four year absence and the start of the season was eagerly awaited. But it was to be a tough fight to maintain their status; from the very start to the very end the threat of an instant return hung over their heads and they only got in the top half of the table for one week in September.
The main weakness was up front where they did not have sufficient goalscoring power. The club kept stating they were trying everything possible to make a transfer breakthrough and that funds were available; but in reality they lacked the cash required to get the quality of player they required.
Survival was based on grinding out results and Harvey's team were not afraid to dish out the rough stuff; bringing them criticism from opposing managers. They eventually finished in 15th; four points above the drop zone.
An embarassing exit in the Second Round of the League Cup and a Fourth Round home defeat in the FA Cup rounded off a disappointing season.
Departures included Stan Anderson and Trever Hockey.
