Arsenal came from behind to draw at home to Fulham.
Fulham took the lead under just 60 seconds through Periera after a mistake from Bukayo Saka.
Vieira, who came on in the second half won Arsenal a penalty, which was converted by Saka. Eddie Nketiah gave Arsenal the lead via a lovely assist from Vieira.
However, a last minute strike from Palhinha gave Fulham a point.
