Arteta hooked Calafiori at half time, perhaps unwilling to play with 10 men for the sixth time in the Premier League this season, and on came Kieran Tierney.
Nwaneri was the brightest spark of an attack lacking any threat, but it said a lot about Arsenal’s first half that their best moment came from left-back Riccardo Calafiori.
For the third season in a row, it looks like the Premier League title will evade Mikel Arteta’s side as surely Liverpool cannot be caught now.
They are six points off Arsenal in second, but crucially the gap to Newcastle in sixth now stands at six points.
As for Arsenal, Arteta said before this game he would give up on the title “over my dead body”.
