Calafiori was one of four changes made by Mikel Arteta for the trip to Sunderland, and he went the full 90 minutes as Arsenal ground out a 2-0 win at the Stadium of Light. The Gunners sealed the win with Bruno Guimarães’ second-half strike and a Bukayo Saka penalty in stoppage time, securing a fourth win from four and a perfect record at the top of the table.
Gianluigi Donnarumma also had a crucial role to play in Manchester City's 1-0 win against Manchester United. The Italian goalkeeper produced a stoppage-time save from Bryan Mbeumo to preserve City's clean sheet and keep them level with Arsenal at the summit.
Sandro Tonali's Tottenham side drew 0-0 against Everton, while Honest Ahanor got his first Premier League start for Crystal Palace. Michael Kayode replaced Aaron Hickey in the 71st minute for Brentford, and Michele Di Gregorio was an unused substitute for Bournemouth. Matteo Ruggeri was named on the bench for Aston Villa.
Calafiori will look to continue his impressive form for Arsenal in their next match, while Donnarumma will aim to maintain his clean sheet record for Manchester City.
