The Arsenal fans loved Lucas Torreira before he even pulled on the red shirt.
And they have been calling for the Uruguayan to be handed a place in Unai Emery's starting Xi.
The Spanish head coach has so far been reluctant to use the 22-year-old from the start as he adapts to life in the Premier League, instead giving him cameo roles from the substitutes' bench in all five Premier League games.
The diminutive midfield man got 45 minutes on Saturday, replacing Matteo Guendouzi at half-time, and his impact was almost immediate, as Granit Xhaka opened the scoring from a free-kick four minutes after the interval.
And it was he who changed the game in Arsenal's favour, according to Newcastle legend Alan Shearer on Match of the Day.
The little Uruguayan had his own fan club at the game at St James' Park on Saturday and there were additions to that fan club in the BBC studio on Saturday night.

Shearer said: "Torreira came on and he changed the game, he came on and bossed the midfield, his first thought was 'can I go forward, can I get it into the centre-forward'. They get that free-kick and they score from it.
"Arsenal were much the better team in the second half and he just kept everything moving, everything ticking along. They were patient, didn't hurry things, got into good positions.
