Gabriel Jesus was on fire scoring his first two competitive goals for Arsenal in a thrilling 4-2 victory over Leicester city on a sweltering afternoon at Emirates Stadium.
The Brazilian scored two goals in as many minutes, the second coming after Jamie Vardy inadvertently flicked a corner to the back post.
The Brazilian was unfazed by the heat in north London, which reached 33 degrees, scoring a brilliant first goal with the help of a slight deflection (23) and then nodding in his second (35) to mark his first Premier League appearance for the Gunners.
Vardy had a penalty decision given and then rightly taken away after VAR Mike Dean advised referee Darren England to re-assess the minimal contact between Ramsdale and the striker just before half-time.
Temperatures rose in the stadium when a replay was shown on the big screen, with the Foxes frontman loudly booed.
After the break, the action and goals kept coming, with Leicester twice taking control of the game and Arsenal responding twice as quickly.
An own goal by the otherwise outstanding William Saliba (53) was immediately followed by a similar poor error by Leicester goalkeeper Danny Ward, which allowed Granit Xhaka to sweep in, two minutes later.
Gabriel Martinelli’s second of the season came 60 seconds after James Maddison’s drive (74).
Arsenal easily could have scored more; Xhaka and Jesus both struck the woodwork in either half; however, two victories in a row boosts their confidence early in the season, while Leicester were once more exposed by a set-piece and appeared to be in need of reinforcements.
