I think it's safe to say that most people who follow the Whitecaps closely know that Robbo's preferred formation is a 4-2-3-1, however, he's shown that he's not afraid to go to a 4-4-2 and sometimes 3-5-2 if needed. I've come to accept that the 4-2-3-1 is, for now, here to stay and the 4-4-2 is widely used, however, let's look at a few different options, and what players, when fully healthy, could fill those roles.
I'd like to see a 4-1-4-1:
As much as I've recently ripped on Rivero, at this point in time, I'm not sure Kudo could do any better. Robbo also seems to have sealed this team's fate on Rivero's ability (or lack of) to score goals. That's a different discussion for a different day.
Yes, Rivero is up top alone, however, you could push Morales, Techera and Manneh forward, not necessarily all at the same time, and still have 5-7 men back for any potential counter attack.
Most of the soccer world goes with a 4 man backline, and I'm one of those, but just for fun, let's see what the Caps might look like in a 3-5-2.
In this formation, Laba, would still be a holding mid, however, I'd have him playing deep, creating almost a 3-1-4-2, allowing him to be a quasi-centreback if needed. I am not a big proponent of a 3-5-2 given the Caps current roster make up.
Why Perez and not Kudo? Having Perez in there gives a different dimension for defenders to deal with. Nothing more, nothing less.
