A second-half double from Zander Diamond gave the Dons a 4-2 win over the champions in a sensational game at Pittodrie.

Scott Brown equalised for Celtic after 25 minutes to cancel out Gary McDonald's headed opener for the home side a minute earlier.

Stuart Duff restored Aberdeen's lead with a clinical finish after 31 minutes before Socceroo McDonald headed his side back level after the break.

However Diamond's double, both headers from Charlie Mulgrew deliveries, gave the Dons their first win over Celtic at Pittodrie since 2001.

Motherwell's revival continued as it romped to a shock 4-0 win over Dundee United.

The clash at Tannadice should have strengthened United's case for holding onto third place this season but it was instead left reeling as Marc Fitzpatrick, Maros Klimpl, David Clarkson and Chris Porter all helped themselves to a goal.

Motherwell plunged as low as joint-bottom of the SPL earlier this season but three wins from four games means it has now hauled themselves into mid-table and could now even be belated challengers for the 'best of the rest' tag they claimed last term
