Increasingly frequent reports this week have linked England international Welbeck with a surprise switch to the Emirates Stadium, with the latest speculation suggesting that Arsenal are preparing a bid of £12 million for a player that the Red Devils are believed to value at around the £16 million mark.
Such a potential deal appears very much to have divided supporters of the respective Premier League giants, although ex-Gunners skipper McLintock - who made over 300 appearances for Arsenal during a nine-year spell at the old Highbury between 1963-74 - evidently believes that Welbeck would be a strong signing for Arsene Wenger as his side look to cement their status as genuine title contenders this season.
"I think he [Welbeck] would be a good addition," the 74-year-old Scot was quoted by The Daily Star.
"He is still a young lad, he has had a lot of experience playing for Man United and he would give us a definite option, because last year (Olivier) Giroud was running himself into the ground.
"There were some games where he was very tired and we had no one really to step into that position."
Giroud injury blow
Arsenal's need to invest in a new striker was made all the more crucial at the weekend, with Giroud having sustained an injury to his ankle during the closing stages of the eventful 2-2 draw with Everton at Goodison Park.
With worries abound that the Frenchman could be set for a lengthy spell on the sidelines, Wenger will be forced to rely upon the likes of young Yaya Sanogo unless he can quickly seek an alternative replacement prior to Monday's transfer deadline.
Welbeck does not appear to be Arsenal's only target, however, with Paris Saint-Germain striker Edinson Cavani and Queens Park Rangers talisman Loic Remy also said to be on the club's immediate shortlist.
No United future?
Despite retaining a certain sense of popularity with a large proportion of the Old Trafford faithful, Welbeck 's career appears to be stalling somewhat and many expect him to depart Manchester United before the end of the window.
Indeed, new Red Devils boss Louis van Gaal - who was rendered speechless on Tuesday evening as his side were routed 4-0 by League One side MK Dons in the second round of the Capital One Cup - is keen to offload Welbeck soon, with the 23-year-old believed to have been told that he is free to leave the club.
Arsenal's North London rivals Tottenham are another top-flight outfit to have been closely linked with his signature, but it remains to be seen if Manchester United will be content to see him join another club with similar domestic aspirations to their own.
