"It is a great performance against this team but we are a little disappointed with the result considering the chances we had," he told Sky Sports.
"It was important to win with a clean sheet ahead of the second leg at Liverpool, we had a strong, fantastic game. I think this was the first time Liverpool had just one chance in a game.
"We defended together very well and we played good football with many chances. In the end we were unlucky and unhappy with the result because we know away at Liverpool will be very difficult, but it was a good performance from my team."
