The Arsenal striker was tracked by United, City and Juventus after announcing his intention to leave Arsenal but ultimately chose Manchester United and has been undergoing a medical ahead of a move to Old Trafford.
Seen as a player that can help United reclaim the Premier League title from Man City, largely Van Persie signing has been positively received.
But former Man City striker Rodney Marsh is sceptical and questions what message Sir Alex has sent out by signing the 29 year old as he told BBC Sport:
“Van Persie is Ferguson’s last-ditch effort to reclaim the title back from Manchester City.
“It tinges a touch of desperation on Manchester United’s part based on the fact that they have spent an incredible amount of money for an ageing player.”
But whilst he questions Sir Alex’s decision to bring Van Persie in, he acknowledges that Van Persie will make United a serious threat to Man City’s hopes of retain the title:
“I still feel City are the favourites, they are the team to beat. But when you throw in the wildcard of Van Persie, he is probably the one player that could take Manchester United back to the top.”
