Arsenal goalkeepers past and present came up against each other at the weekend.
After conceding eight goals against Southampton a week earlier, Vito Mannone looked like a goalkeeper lacking in confidence against Arsenal.
Facing his former club, Mannone, made a terrible mistake late in the game to allow Alexis Sanchez to double Arsenal's lead and pour on further misery.
The consolation is Sunderland were beaten already when he made his gaffe, but that will do little for the confidence of a goalkeeper who really needs as much as he can get right now.
Sunderland signed Costel Pantilimon from Manchester City in the summer, and there is a growing case to hand him a chance and take Mannone out of the spotlight.
That could backfire and dent Mannone's confidence further, but manager Gus Poyet knows results are imperative, and such a decision could be necessary if the Wearside club are to bounce back during November.
