I haven't seen much, no, but enough to know how they and Guardiola plays, and that Ribery and Robben are not inside forwards. I mean, are you only looking at Robben's goal return to come to the conclusion that he's not a winger? Or maybe you think a wingers job is to just get crosses in?
Robben and Ribery start wide, in a wingers position, where they can stretch teams. Yes, when they get the ball they often cut in and link up play or shoot. When they haven't got the ball, they will look to make darting runs from between the full back and centre back. That's what wingers do. That does not mean they're inside forwards. Inside forwards, start narrow, and more or less play like second strikers. For example, look at the way Liverpool play with two players just in behind the striker. That's what I would call inside forwards.
Below is a heat map of Coutinho's touch map against City

Now look at the different between Robben's touch map in Bayern's latest game against Hannover

Now, from looking at the two touch maps, it's clear to see that the both players share different jobs. One starts narrow, one starts wide.
As for you not wanting us to not want us to play with the same style as PSG, well, like I said, we have to play to our strikers strengths, and PSG play some pretty attractive stuff, at times.
Rooney, in my opinion, is closer to the likes of Lewondowski, Ibra, etc, in the way he likes always play down the middle, drop off and link up play. I think he'd make for a great false number 9 if he had wingers around him, who keep the width, and make runs in behind the defence, where Rooney can use his passing range to find them.
We clearly have different ideas of what a winger is.
