Former Juventus midfielder Emerson says they face a massive test at Champions League opponents Borussia Dortmund.

Juve will go to Germany for the second-leg defending a 2-1 lead.

"It will be tough, Borussia Dortmund has recovered from a difficult period, but they're fine now.

"There are no easy games in the Champions League, going to Dortmund there will be a special atmosphere.

"There will be sixty thousand fans to push the team, all dressed in yellow and black."
