"We are delighted to sign a very young and talented player, one we believe has the potential to grow into a very good player," Dynamo head coach Owen Coyle said in the teams press release. "He has a good physique, can score goals, has pace, and is intelligent. He will have to adapt to MLS, but we look forward to another exciting young player joining the Houston Dynamo."
