Arsenal striker Danny Welbeck made his return from a 10-month injury layoff on Friday as the Gunners' under-21s stormed to a 4-1 victory against Brighton and Hove Albion.
The England international completed 60 minutes before being withdrawn in the second half, with manager Arsene Wenger likely to be closely monitoring his comeback progress.
Welbeck's return will have delighted fans, but emerging starlet Reiss Nelson was the man of the moment against the Seagulls, scoring the opener before setting up two more goals inside 20 minutes.
Three points saw the north Londoners move to the summit of the Under-21 Premier League Division Two with a game in hand over second-place Derby County, who are now one point behind Andries Jonker's leaders.
