Video: Brighton 0 - 1 Arsenal (Dec-29-2020) Premier League Highlights

Alexandre Lacazette scored 21 seconds after coming off the bench to give Arsenal a hard-fought 1-0 win over Brighton.

The striker collected Bukayo Saka's cut-back with his first touch after replacing Gabriel Martinelli in the 66th minute at the Amex Stadium before composing himself and firing a clinical finish into the bottom corner.

The goal secured a second consecutive victory for Arsenal following their 3-1 win over Chelsea on Boxing Day, giving them back-to-back Premier League wins for the first time since their opening two games of the season.
