Striker Welbeck - who impressed with two goals for his country on Monday night as the Three Lions comfortably navigated through what should be their toughest Euro 2016 qualifying tie away to Switzerland at St. Jakob-Park - graduated through the youth system at Old Trafford, but was obviously deemed surplus to requirements under Louis van Gaal this season after being offloaded to Arsenal on deadline day for a reported £16 million fee.
The arrival of Colombian talisman Radamel Falcao - who completed an initial loan move to Manchester United last Monday and should join the club permanently from Monaco in 2015 if he impresses under Van Gaal - smoothed the sale of Welbeck somewhat, although some supporters were still slightly disappointed to see such a popular figure depart.
Arsene Wenger's decision to reinforce his own strikeforce with the 23-year-old has not been universally well-received in North London, although Butcher appears confident that Welbeck has the talent to succeed in his new surroundings.
"Man United will regret selling Danny Welbeck to Arsenal," the former Ipswich, Rangers, Coventry and Sunderland centre-back said in an interview with talkSPORT.
"The way Arsenal play, and the chances they’ll give him, will make Man United regret their decision."
Butcher seemed to think the price involved in the Welbeck deal also represented somewhat of a steal, with this summer's transfer window in particular characterised by a number of big-money purchases that far exceeded market value.
"He’s enjoying his football at the moment. Arsene Wenger must be purring because it is a superb piece of business," he added.
Welbeck - potential for success
Having proved on Monday that he is fully capable of scoring when deployed in his favoured role up-front, a confident Welbeck certainly could thrive at the Emirates Stadium, proving his seemingly extensive list of doubters wrong in the process.
Olivier Giroud's foot injury - sustained during the 2-2 draw with Everton at Goodison Park last month - has left Arsenal somewhat short of reliable options in the final third, despite Wenger's insistence that he bought Alexis Sanchez in order to utilise the former Barcelona man primarily through the middle of the pitch.
Young Frenchman Yaya Sanogo - who also scored on international duty this week with a well-taken volley for France's U21 side against Iceland - has tried his best to fill the void in recent weeks, but has been on the receiving end of a lot of criticism from Gunners fans for a perceived lack of effectiveness.
