Alaxandre Lacazette sent an important message to Unai Emery
The former Olympic Lyon striker who came off the bench to replace Nigerian winger Alex Iwobi sent his club coach a message by changing the rhythm of the game when he forced West Ham debutant, Issa Diop to deflect the ball into the net.
The cacophony reduced abruptly when West Ham converted striker Marco Arnautovic put the Hammers in front at the Emirate Stadium before the informed Spanish left wing-back Nacho Monreal brought his team level again.
The strident noise increased, but shortly after the visitors changed their approach and were more likely to score, the tranquillity from the club supporters made the coach opted for an extra striker in the second half.
Lacazette came in and created clear-cut chances until he forced Diop to put his name on the score sheet.
While the pressure mounted on coach Pellegrini who urged his team to push forward before the long-awaited substitute, Danny Welbeck in his first appearance changed the scoreline to 3-1 in the penultimate minute of additional time.
Regardless of injury quandaries and a lack of steadiness during his debut season in England, Lacazette still found the back of the net 17 times and he sent out a strong message to his boss with his imposing performance against the Hammers.
