“We wanted to start strong in a high pace and committed way.
“We started wobbly in the first 20 minutes against Southampton. We wanted to be consistent in our pressure no matter the score and we did it very well in the first half. It was in and out in the second, which was understandable.
“Ideally you want the perfect game but you never get it. We got nearly the perfect first half and that is not bad.
“Football doesn’t care for history and the anniversaries, just the result on the day. Today we had a good performance.”
