Ante Razov is out for the season but that doesn't mean Chivas USA's done. There is still enough quality on the team to fill in for Ante but the club will need to find a way to fill that void, and soon.
What's best for the team is probably to put Laurent Merlin alongside Maykel Galindo. Merlin won't draw the attention from defenders that Razov did but that might be a good thing, since Merlin is a fine distributor of the ball.
Really, though, Razov's absence just means the midfield needs to contribute even more than it has. The pressure will fall squarely on the shoulders of Francisco Mendoza and Sacha Kljestan. If those two can add some consistent finishing in the playoffs, teams will be forced to pay more attention to the midfielders and open up more room for Galindo and Merlin.
Another option might be Ramon Nunez. He's a bit small - he and Panchito are from the same mold - but he's got skill. He hasn't really shown his full worth yet but that's more because he hasn't been getting a lot of minutes.
Still, though, Chivas USA isn't about Ante Razov. It's not a team that's geared toward any one player, as great a player Ante is.
