The Colorado Rapids completed the signing of midfielder Bismark "Nana" Adjei-Boateng from Manchester City on Tuesday.
Terms of the transfer were not disclosed, though the Rapids used targeted allocation money in the deal.
"Bringing Nana to the club was a key part of our offseason strategy and we're delighted to welcome such a promising young talent to our club," Rapids director Padraig Smith said in a statement.
"He's a powerful player with the drive and energy to be effective box to box. He possesses great technique and vision and influences the game on both sides of the ball.
