I'd really like to see us run a 4-3-3. I think our players have the skills for it and it fits with our lineup, but it's probably a tough call at this stage of the season.
When we have the ball, I'd try to play it this way:
Osorio, Gilberto and Moore play an inside-out game, where they make diagonal or horizontal runs that pull defenders with the others running into the space created. This would give Moore and Oso lots of options for passing and they'd have support from Bradley (inside), Bloom (outside) or Gilberto (up front) providing the triangle for passing. Moore does a good job of getting into the mix, knocking balls to Gilberto and they would be welcome to swap positions when they saw fit, with Osorio filling in behind.
Bradley provides the push up the middle, supporting Oduro's mad dashes down the right or giving the Oso/Moore/Gilberto trio a great option to switch back around. He can also, as he has shown, arrive late after the front trio has taken the ball deep. Him and Osorio both have the passing vision for this and having Warner mopping up would allow Bradley a bit more liberty to push up, although he would still very much have a key defensive role. Bloom has the legs to get up and down the pitch, and although I much prefer him on the right, he's probably our best option on the left until Morrow gets back, unless Ashtone Morgan somehow makes a triumphant return. Hagglund would have to be a bit more defensive on the right side, given that Oduro is going to be going forward with freedom and Bradley is going to be the one running into that channel behind him if play goes down the right.
By drawing defenders toward the potent trio of Osorio, Moore and Gilberto on the left, it gives Oduro the space he needs to run at defenders and pull them out of position, opening up space for said trio or for a trailing Bradley. If the ball stays on the right, Osorio then comes over to support toward the middle, Hagglund and Warner keep a relatively high line and act as an outlet if the cross isn't on, but also guard against a quick counter. In that scenario, Moore is the far post man and Gilberto either shows for low passes or drives toward the penalty spot for the cross.
Defending, we rely on high pressure from Moore and Oduro, as well as Gilberto's ability to run forever and drop back to help the midfield. Bradley drops back in front of the D to help Warner and Osorio fades left to support on that side. Given the speed of Gilberto and Oduro, this would also allow us to recover balls with the option of Oso or Bradley using their vision to spring the counter.
Anyway, maybe I play too much Football Manager, but I see this as a fairly dynamic system that would work with the talent we have, give us more options and still have good shape without the ball, provided the players play their roles. Am I off base with my assessments of any of the guys? I've watched a lot of the matches on MLS Live, but not every single minute of every single game.
