On Monday, the club will head to Florida for a 10-day stay at Lakewood Ranch in Bradenton.

But before that, Coach Ben Olsen is getting his incomplete team together. United is still aggressively pursuing reinforcements from overseas — namely, a striker — and will shuffle numerous trialists through camp.

Maicon Santos, the Brazilian forward who has toiled in MLS since 2009, has officially joined the club, but no other veteran acquisitions have been finalized.

“Don’t worry, guys, we’re going to have a team,” Olsen said to a handful of shivering reporters. “I know you are all very concerned about this, but we will have a team.”

While everyone awaits new arrivals, several players are out. Goalkeeper Bill Hamid is on U.S. national team duty for another week. Perry Kitchen is nursing a toe injury, suffered while training with Freiburg in Germany. Ethan White is recovering from a knee injury while on a U.S. under-23 assignment. Josh Wolff needs time for a stress fracture in his foot to heal. First-round pick Nick DeLeon is recovering from a quadriceps injury suffered at the MLS combine.

All are expected to participate soon.

Chris Pontius (broken leg in September) is still several weeks from returning to full workouts.

“These first couple days are just to get reacquainted with the ball — as many touches as possible for the rostered guys and the trialists, we’ve got to take a look at,” Olsen said. “We’ll cut that number down before we go to Florida, so it’s important for us to push them.”

In Florida, new signees and trialists will join the club.

The roster gaps at the start of camp aren’t a problem, Olsen said.

“As much as I’d like to have everyone right now,” he said, “it’s not a bad time for [the injured players] to recover in the next week or two [when] we have a full squad. That’s about when you want it anyway. These first two weeks are really about getting a base of fitness and touch the ball as much as possible.”

The new faces

Current trialists include former Chicago Fire goalkeeper Andrew Dykstra (a Woodbridge native who played at Virginia Commonwealth); forward Yoni Berhanu (Potomac, George Washington University); midfielder Seth C’deBaca (Georgetown); forward Levi Houapeu (Germantown, UMBC; Philadelphia Union); forward Matt Oduaran (University of Maryland); and goalkeeper Will Swaim (Ellicott City, University of Maryland).

The most intriguing trialist: Jed Zayner, who was United’s starting right back at the beginning of the 2011 season. Hamstring injuries and a knee problem limited him to four league matches. The hamstrings healed, but after surgery, the knee has little cartilage remaining. United declined to exercise his option but invited him to earn a contract.
