Forest, who have been one of the Championship's most consistent performers in recent seasons, were no match for Kewell's League Two club in a behind-closed-doors friendly.

Davis Keillor-Dunn opened the scoring after just 15 minutes before Zak Dearnley doubled the advantage just 15 minutes later.

Oldham then held on comfortably to win the game, with Kewell saying Nottingham fielded a strong side in the second half - having recently shelled out on new recruits Jack Colback, Tyler Blackett and Lyle Taylor.

Nottingham refused to confirm which players they fielded in the game. Oldham also earned a solid result in their first friendly last week, drawing 3-3 with Accrington.
