How are you going to provide a killer ball through the defence when your strikers are RVP and Rooney?
Think this problem comes through a lack of wingers, especially in a 3-5-2. Leads to full backs just becoming narrower and essentially doubling up on RVP and Rooney. In Giggs/Ronaldo(lol)/any ****ing winger days, they would stretch defences, then bam over the top to one of Rooney/other strikers due to good movement.
