Welbeck scored United's fourth goal in their comfortable 4-1 win over Nigel Clough's Championship side but it was the manner of his celebration which is said to have met with Ferguson's disproval.
Welbeck stood in front of the travelling United fans with his chest puffed out after completing the scoring with a brilliant first-time curling shot into the far corner.
A source says in the Sun
: "Alex was very angry about the way Welbeck celebrated his goal at Derby. He felt there was a touch of arrogance about it."
Welbeck is highly regarded at United and it is thought Ferguson's decision to drop him into the reserves was a ploy to keep the young upstart grounded.
The teenager responded in positive fashion, scoring twice against Oldham as United came from 4-1 down to win 5-4. His positive response could land him a recall to United's first-team squad for their Premier League contest against Blackburn on Saturday.
Welbeck's celebration was on the tame side when you compare it to five other top celebrations.
1. Temuri Ketsbaia When he scored against Bolton in 1998, Newcastle striker Ketsbaia ripped off his shirt, ran over to an advertising board and began to kick it, angry at his role as a substitute.
2. Roger Milla The Cameroon striker set the 1990 World Cup alight with his famous wiggle. The 38-year-old scored four goals in the tournament and marked them all with his manic hip-gyrating by the corner flag.
3. Peter Crouch The giant striker become known for his robotics moves at a pre-World Cup party at David Beckham's house in 2006, and he put them to good use on the pitch, celebrating his strikes against Hungary and Jamaica.
4. Paul Gascoigne England players were photographed on a drunken night out in the build-up to Euro 2006, with Paul Gascoigne and Teddy Sheringham shown sinking their drinks in a dentist's chair. So when Gascoigne scored his goal against Scotland at Wembley, the 'Dentist's Chair' celebration was inevitable.
5. Craig Bellamy The striker found himself in a storm before Liverpool's match at Barcelona last season after chasing team-mate John Arne Riise with a golf club. But when the Welshman struck against the Spanish giants he couldn't resist taking a swing.
