United States forward Jordan Morris is set to travel to Bremen, where he will continue his trial with the Bundesliga club following Werder's winter training camp in Turkey.
Morris, 21, confirmed to reporters that he will make the trip back to Germany with the squad on Saturday.
"I will stay in Bremen for a few days. We'll see what happens after that," the attacker told local paper Kreiszeitung. "They are all very good lads. It's always fun to play against strong players. I am happy and excited."
Speaking to reporters in Bremen's training camp, club coach Viktor Skripnik said he will continue to watch Morris.
"On the first real day of training, the impressions are very positive," Skripnik said after he saw Morris play in a training match. "I am surprised in which great shape this young man from America is. And he's got a good understanding of football, looks for open spaces."

Earlier this week the club's CEO Thomas Eichin said "he reminds me of my time in ice hockey," adding that he has been impressed with what he has seen of the former Stanford player so far.
"He could be a creative transfer," Eichin said on Wednesday.
Morris' MLS rights are held by the Seattle Sounders, but he could still sign for Bremen on a free transfer.
At the MLS SuperDraft on Thursday, league commissioner Don Garber said it was "very important" that Morris stay in the United States.
"We hope it will happen, it may not happen," Garber said. "I don't want to say it's the 'most important' thing in the event that it doesn't come to fruition.
"But Jordan represents for us the future of our league and I think the [United States] federation probably views Jordan as the future of the national team, handing the mantle over from those who really were able to drive it in the past.
"I hope like heck we can get it done.
Bremen attacker Anthony Ujah said he already realised that Morris "is very, very fast, and speed is always important."
Kreiszeitung reported that Morris looked like a mix of Hamburger SV attacker Pierre-Michel Lasogga and Manchester United and England star Wayne Rooney.
Morris recently announced on Twitter that he was giving up his final year of eligibility at Stanford to "pursue a professional soccer career," and traveled to Germany after accepting the Hermann Trophy as the best college player in the U.S.
Also on Thursday, Werder Bremen captain Clemens Fritz announced he will to retire this summer.
The 35-year-old wrote an open letter on his own website explaining his decision to call it a day when the current season ends.
"I've given extensive thought to my personal future over recent days and weeks and after careful consideration, I have reached the decision that I will end my playing career after this season," wrote the midfielder. "It was always important to me to be able to determine the end of my career by myself.
"An involuntary ending was always a nightmare of mine. I would like the fans to remember me as a player who was always physically capable of giving everything for this wonderful club to the end."
Fritz has played 256 Bundesliga matches for Bremen and scored four goals. In addition, he played 21 times in the Champions League and scored a crucial goal in qualifying Bremen for the Champions League group stage with a playoff win over Sampdoria in 2010.
