Newcastle legend Shearer hails Man Utd's awesome foursome
"And, yes, I include the fantastic four from 1999 of Andy Cole, Dwight Yorke, Teddy Sheringham and Ole Gunnar Solskjaer.
"On Friday Ferguson targeted the 100-goal barrier in the league for his team - and already they have 29 from 11 games.
"Add to that nine in four Champions League games and five in two Capital One Cup games and it makes an incredible 43 goals in 17 games this season.
"It is not just about relying on one man in Van Persie - they have had 13 different scorers this season.
"Van Persie is the main man and his link-up play with Rooney makes it look like they have been together for years.
"More goals will come for Rooney undoubtedly as he is world class. Welbeck needs to improve his goals-per-chances ratio but his workrate opens up spaces.
"Then we have Hernandez, the hat-trick hero from Villa Park on Saturday."
