After new United manager Louis van Gaal loaned Columbian sensation Radamel Falcao on transfer deadline day, it left many scratching their heads as to how the Dutchman would accommodate his embarrassing abundance of attacking options.
With Rooney as first team captain it seems he is a nailed on starter each week, so that led many to suggest it would be either Van Persie or Spanish playmaker Juan Mata that would make for the ex-Atletico Madrid man.
Former Arsenal striker, Van Persie believes United are stronger with himself, Rooney and Falcao all in the first-11, and says they are constantly in discussion as to how they can improve their cohesion.
He told Fox Sports News Australia: "We want to play together.
"We are constantly talking to each other [on] how we can improve our game together. Everyone feels that we are together that we are stronger.
"It's quite interesting to see one of those conversations because we all have the target. We want to win games. We want to share success. I don't think we have a confidence issue if I'm really honest."
United supporters and neutrals got their first glimpse of Van Persie, Rooney and Falcao together in the 4-0 romping of QPR almost a fortnight ago, and then again in the dismal 5-3 defeat to Leicester City last Sunday.
In the Leicester clash the United attack looked impressive for the most part, and it seemed that the trio's discussions about cohesion had paid immediately with Falcao assisting Van Persie for the first and Rooney setting up Di Maria for the second.
It's just a shame for United fans that the squad do not have the same cohesion whilst defending.
