The 33-year-old believes that his team have a good chance of progressing to the quarter-finals of the competition after scoring two away goals at the Donbass Arena.
"We can live with the 2-2, even though there was more in this match for us. But the 2-2 leaves us with all chances open for the second leg," he told Sky Sports News.
"We had a grip on the match in the first half. The goal was unlucky and Donetsk is a strong team. But we were way more compact than in the last matches."
However, an 87th-minute header from Mats Hummels cut short their celebrations.
