Chelsea forked out a mammoth £53million to secure the services of Werner before the start of this campaign. The 24-year-old settled in quickly scoring eight goals in his first twelve games for the Blues in all competition.
Werner came under intense scrutiny in recent weeks after failing to find a league goal since he scored against Sheffield United in November.
The former Stuttgart man has been excellent since the appointment of Thomas Tuchel as the new Chelsea manager at the expense of Frank Lampard, but goals were hard to come by.
Werner was influential against the Magpies as he was involved in all two goals as Chelsea secured their fourth consecutive victory.
"First half was really good from us, we played very good football. Happy that I scored finally and there's still a long way to go but if we keep going like this is will be a good end for us,” Werner said after the game.
"As a striker you always want to score, the last month was hard I was not happy with not scoring. But at the end it's a team sport, when we win everything is good. Helping my team with assists and glad I scored.
"For a striker it's worse when you can't get in the right situations and have the chances. I've had a lot of chances which I've missed, my team brought me a lot of situations where I could score, when I keep going the goals will come like I did and the assists as well."
