2. Nick Pope - 7
Made a smart save to deny Julian Alvarez in the 18th minute. Routine save to Grealish later in the second-half. Commanded his box well. | Getty Images
3. Tino Livramento - 8.5
The most impressive out of the three full debutants. Strong defensively up against Jack Grealish and then Jeremy Doku. Attacked brilliantly down the right. Man of the match. | Getty Images
4. Jamaal Lascelles - 7
An important interception to prevent a City cross from reaching the box in the first-half. Very good in the air. | AFP via Getty Images
