Pre-game, the Crew paid tribute to Kirk Urso - the young midfielder who died recently - and Arena suggested that perhaps the 1-1 draw was a fitting result for both sides.
"It's certainly a very difficult situation," he said.
"We feel for the Urso family and the Crew in this sad time and tragic event. We hope that time helps heal a little bit here. That can't be an easy situation for the family or the organization.
"We wish our very best to the Urso family and the Crew. Anything we can do to support them, we would certainly do that."
He added: "At the end of the game, we positioned ourselves to win the game and you can't ask for much more.
"It's always good to get a point on the road, but we would have obviously preferred three."
Jairo Arrieta opened the scoring in the 48th minute before Robbie Keane netted his 11th goal of the season to keep the reigning champions fourth on the Western Conference table.
