A fiery encounter at St James’ Park saw both sides shown several yellow cards but clear chances few and far between in the first half.
The biggest talking point of the first half came as Kai Havertz cynically fouled Sean Longstaff on the touchline but referee Stuart Attwell only showed the Arsenal forward a yellow card. Several Newcastle players, including Longstaff were then booked for protesting the decision.
But with neither goalkeeper really being tested in the opening 45, the sides went in at 0-0.
