On the back of signing his new long-term deal with the club, Nketiah led the line for a senior-looking Arsenal team in the first half, donning his new number 14 shirt in the process.
Mikel Arteta also got 45 minutes out of Thomas Partey following his return from the thigh injury that kept him out of the final few weeks of last season, as the club's internationals enjoyed an extended break.
