Alex Lacazette smashed in a late winner as we eventually shook off a spirited Cardiff side in Wales.
The France striker found the roof of the net from a narrow angle, set up a goal for Pierre-Emerick Aubameyang and even hit the post - not a bad return on his return to the starting line-up.
Harry Arter should have given Cardiff an early lead when he blazed over after intercepting a pass from Petr Cech that was meant for Matteo Guendouzi.
Instead it was Shkodran Mustafi who opened the scoring. The centre back made a darting run to the near post to meet Granit Xhaka’s corner and powered a header into the top corner.
