LONDON (Reuters) - Tottenham Hotspur still have work to do to reach the next round of the Champions League despite a convincing 3-0 victory over Borussia Dortmund in their last-16 first leg on Wednesday, said coach Mauricio Pochettino.
Tottenham stunned the Germans with a goal two minutes after halftime from Korean forward Son Heung-min and struck twice late in the game through Belgian defender Jan Vertonghen, who was deployed in an unusual left wing back role, and substitute Fernando Llorente.
