Newcastle continue to be a positive surprise this season and remain fourth in the Premier League, just four points behind second-placed Manchester City.
But Saturday's match away to Bournemouth can probably still be considered a miscalculation, as the team "only" drew 1-1 against the second-placed team.
The Argentine gave the home side the lead after half an hour of play in an entertaining first half.
Newcastle had most of the possession, but created very few hot chances until the 1-1 equalizer that came in stoppage time in the first half.
Miguel Almirón was then able to coolly place the ball into the far side of the goal post after the goalkeeper returned a first shot from Sean Longstaff.
The goal was his tenth of the season, which gives him a joint sixth place in the scoring league.
Alexander Isak made his fourth league start of the season but was not responsible for any big game.
In the 69th minute, he got a decent chance, but went on the force and shot high over.
Instead, it was Bournemouth that came closest to victory.
In stoppage time Dominic Solanke had a finish which was saved on the goal line by Kieran Trippier.
The match ended 1-1.
Heavy for Newcastle was that the goalscorer Miguel Almirón and teammate Allan Saint-Maximin went out injured in the second half.
17 consecutive games without defeat (nine wins, eight draws) is a club record for Newcastle, but the last time they managed such an impressive streak (2010) was not in the Premier League but in the second highest league.
