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.
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.
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.
