Their movement, [in] the second half, we controlled better than the first. Tactically, the first goal is one mistake but because we played that action more with heart than head.”We had two players trying to win the ball with Harry Kane – we needed one to cover. The second half, we did that work perfectly.”With our supporters, we created a very good atmosphere.
