Former Oldham Athletic manager Lee Johnson came back to haunt his old side as Barnsley brushed aside the 10-man Latics 3-1.
Oldham Athletic interim manager Dean Holden has warned his players not to get too ‘emotionally involved’ when they face former boss Lee Johnson’s new side Barnsley on Saturday.
Carl Winchester had put Oldham ahead on the stroke of half-time, but Joel Grant’s equaliser ten minutes after the break and Hayter’s late winner mean Oldham have now lost four of the last five.
Two Preston goals in each half, including a first half-strike from ex-Latics loanee Daniel Johnson, settled the game 4-0 as Oldham lost their third straight match.
Barnsley scored with their first attack when Kane Hemmings got on the end of a Milan Lalkovic cross to poke the Tykes into a 12th minute lead which Oldham never pegged back.
