Ukrainian midfielder Yegor Yarmolyuk, who moved to Brentford from Dnipro-1 in the summer, made his debut in the first team in an official match.
Egor came on as a substitute in the 72nd minute of the English League Cup meeting against Gillingham.
The Ukrainian team lost in the penalty shootout (1:1, pen. 5:6).
Yarmolyuk, who started the season with Brentford B, has been on the Premier League list for the last few games but has yet to make his league debut.
