You feared Gabriel Magalhaes had gone too early in goading Erling Haaland.
Less than two minutes it took for the Arsenal defender, with a contorted expression overcome by the ecstasy of his side taking an early lead through Martin Odegaard, to reignite his feud with the Manchester City striker by celebrating in Haaland's face.
These two have history, of course. They aren't on each other's Christmas card lists, put it that way.
Perhaps, Gabriel knew what lay ahead. Haaland touched the ball just six times in the opening 45 minutes, completing just one successful pass.
