Sunderland won 3-1 against Gateshead in a friendly yesterday as Phil Parkinson's side prepare for the League One season.

The game gave boss Phil Parkinson the chance to assess his players and he will have been impressed with how the team played and certain individuals.

One who made a positive impression was youngster Jack Diamond from a wing-back role. The 20-year-old spent last season on loan at Harrogate in the National League and starred as they won promotion to the Football League.
