Arsenal’s squad players impressed boss Mikel Arteta as they eventually broke Dundalk’s resistance to win their Europa League group game at Emirates Stadium.
Eddie Nketiah pounced from close range to give the Gunners the lead and Joe Willock blasted a shot into the roof of the net 125 seconds later.
Nicolas Pepe’s brilliant effort from the edge of the box seconds after the restart killed the game off.
They cruised after that but could not add a fourth against the Irish side.
“We gave a chance to a lot of players who haven’t played many minutes this season and it is something really positive because they showed they are well-prepared, they are at it, and they are ready when we need them,” Arteta said.
“They are always in the frame to play. It is not if we lose or win, it is what they bring to the team.”
It was a stark contrast to Spurs boss Jose Mourinho’s criticism of his fringe players as Arsenal’s north London rivals lost 1-0 to Royal Antwerp.
Arsenal – who had never faced a side from the Republic of Ireland before – have now won both their opening Europa League games, while Dundalk have lost both of theirs.
Dundalk made a bit of history as the first team in the 10 years of the Europa League not to commit a single foul in a game.
