The Philadelphia Union have acquired German fullback Kai Wagner from Wurzburger for an undisclosed fee, the club announced Wednesday.

Wagner appeared in 44 matches over the last two seasons with the third-division German side.

"We are delighted to complete Kai's signing as he is an up-and-coming and very physical left fullback with high ability and even further potential," Union sporting director Ernst Tanner said in a statement. "Kai has joined us in Clearwater (Fla.) and we look forward to introducing him to his new teammates and integrating him as quickly as possible."

Wagner, who turns 22 on Feb. 15, joins a youthful Union defense that features 19-year-olds Mark McKenzie and Matthew Real, 20-year-old Auston Trusty, 21-year-old Olivier Mbaizo and 23-year-old Jack Elliott.

"(Wagner is) very dynamic, he's very physical," Tanner said. "He can cover a lot of ground and he's quick. You have somebody who is going in both directions very quick and (there) are not so many players capable of doing this."

The Union open the MLS regular season at home against Toronto FC on March 2.
