Bruce Arena's first squad in his second stint as U.S. coach is made up entirely of Major League Soccer players.

Arena, who replaced Jurgen Klinsmann as the U.S. manager in November, called up 32 players from 15 different MLS clubs for U.S. Soccer's annual January training camp that begins next week in Carson, California.

The camp falls outside of a FIFA international window, meaning clubs in Europe and Mexico did not have to release their players. Last year, Jerome Kiesewetter -- then with German club Stuttgart -- was the only player from outside MLS to attend Klinsmann's final camp.

Arena said he was looking to find players who can help the U.S. recover from its poor start to the final round of World Cup qualifying when the "hex" resumes in March.

"The last couple of games in qualifying didn't go well, so we're looking for some players that are eager to get on the field and make some contributions," he said in a Facebook chat.. "I believe our team, when you look at the entire pool, not only in Major League Soccer but abroad as well, we have enough talent to win games.

"We can score goals. Defensively, we can be strong. Our goalkeeping is solid. Our back line can play a lot better than they have, and I think our top 4-5 players in attack are talented players and depending on who we utilize, we have speed and we have players that have proven they have the ability to score goals at the international level."

Four players -- DaMarcus Beasley, Michael Bradley, Chad Marshall and Nick Rimando -- are still around from Arena's last tenure with the national team, which ended after the 2006 World Cup.

Marshall and Sacha Kljestan have not taken part in a January camp since 2010, while Dax McCarty was called in for the first time since 2011. In all, 13 players return from Klinsmann's 23-man camp a year ago.

"I thought Chad Marshall had a great year in Seattle and I'm really looking forward to seeing him in camp," Arena said.

Forward Clint Dempsey was not included following the irregular heartbeat that sidelined him for the second half of 2016, after Arena said last month that he hoped he would be available to train. However, the MLS champion Sounders still lead all MLS clubs with four representatives on the team.

Arena gave a first call-up to Sebastian Lletget, his former midfielder in his previous job as LA Galaxy coach, while other uncapped players in the team include defenders Taylor Kemp, Keegan Rosenberry and Walker Zimmerman, and midfielder Chris Pontius.

Kekuta Manneh and Stefan Frei were included, though they are still in the process of completing their eligibility requirements to play in games.

"Thirty-two is a big number, for sure," Arena said. "Typically in camps you'll be in the 20s, probably close to 25. But as we evaluated the players in Major League Soccer I thought there were a number of players that needed to be rewarded for the seasons they had, and that's why we've invited this large number into camp. At the same time, I realized that we left some players at home. It's been a difficult task."

Following camp, the squad will face Serbia in a friendly on Jan. 29 in San Diego (ESPN2) before facing Jamaica in Chattanooga, Tennessee, on Feb. 3.

Jozy Altidore can earn his 100th cap for the U.S. by playing in one of those games, though the striker has been given permission to arrive two days late to camp. McCarty will join the team on Jan. 16.
