“The second goal was very important because 1-1 going to Lyon might tip the balance to them, but at 2-1 it gives the balance to us,” Friedel told the Spurs website.
“It’s two good teams both trying to progress and it’s by no means a massive advantage, just a small advantage.
“They are going to have come out and try to score and hopefully that will leave it a bit open at the back and could leave chances for us.
“I’m sure it’s going to be a great second leg. The knockout stage of the competition is when these games really come alive and we’re looking forward to it.”
