''I think that whole game was a learning opportunity for Lalas," Berhalter said, as reported by the Columbus Dispatch.
"I think there’s a number of play where he felt he could have done better and that’s why he’s a young player and that’s why he’s learning.
''To me he’s been doing a good job since he’s been playing and as long as he can learn from this, he’ll be fine.''
