Arsenal legend Ian Wright was full of praise for Leandro Trossard after the winger scored his first goal for the club.
Trossard, who joined from Brighton last month, was brought on in the 62nd minute against Brentford as he replaced Gabriel Martinelli, who had struggled to make much of an impact.
Within four minutes of coming on, Trossard found the net with a neat finish to put Arsenal ahead.
The Gunners were unable to hold onto their lead, with Ivan Toney levelling for Brentford with an effort that was allowed to stand despite a VAR check.
