The sight of Noni Madueke flying past defenders and putting dangerous crosses into the penalty area will have been a welcome sight for Mikel Arteta.
And Madueke's performance in Arsenal's 4-0 hammering of Leeds will have been even more well received, given that he was drafted into the starting line-up minutes before kick-off after Bukayo Saka picked up a hip injury in the warm-up.
The 23-year-old created Martin Zubimendi's opener, before seeing his corner punched into the Leeds net by goalkeeper Karl Darlow for the Gunners' second, as Arteta's men moved seven points clear at the Premier League summit.
