Was typically threatening, saw plenty of the ball and linked play up well at times. The best he had to show for his efforts was a wayward strike from 25-yards. Photo: Alex Livesey

12. Sven Botman - 8
On for Lascelles 46: Introduced at half-time and put into the right centre-back position initially. Was excellent with the ball at his feet and launched a number of Newcastle attacks, including the one leading to the opening goal. Was strong in the air too as he kept 1860 Munich at bay. Very early stages but it would seem that the hype is real. Photo: Getty Images
