Reiss Nelson was the star of the show against Nottingham Forest after scoring two goals and providing an assist off the bench.
Nelson replaced the injured Bukayo Saka in the 27th minute of the match when the England international was unable to continue after picking up a heavy knock on his ankle. The 22-year-old was Mikel Arteta's first choice to replace Saka as he made his first Premier League appearance of the season after suffering a muscle injury back in August.
Nelson settled into the game, and his second-half performance took the game away from Forest as he scored twice in three minutes before setting up Thomas Partey for a brilliant long-range strike just moments after. Martin Odegaard completed the rout with a fine solo effort with 15 minutes left to play as Arsenal moved back to the top of the Premier League.
