Substitute Alexandre Lacazette made an instant impact as Arsenal continued their resurgence by scraping a 1-0 win which prolonged Brighton’s miserable home record.

Lacazette, dropped to the bench to accommodate recalled captain Pierre-Emerick Aubameyang, coolly bagged the second-half winner just 21 seconds after replacing Gabriel Martinelli.
