While Manchester United vs Liverpool, and then the Carabao Cup final between Manchester City and Chelsea, occupy the headline slot, Unai Emery's side will fly somewhat under the radar for the visit of Southampton. "The players worked a lot, and we decided to make some changes to bring in new players, to keep up the energy", he said.
Arsenal will welcome Bournemouth to the Emirates Stadium for a Premier League clash on Wednesday, a midweek game that Arsenal will be expecting to win.
Emery has worked hard to iron out the flaws in the 22-year-old's game and Iwobi has shown signs of progress in recent weeks, playing a pivotal role in the two goals which helped the Gunners move into fourth place in the Premier League following a 2-0 home win over Southampton on Sunday.
"It is not the main thing at the moment".
Their best chance of the game had come seconds before Lacazette's opener when Nathan Redmond was through on goal only to fire straight at keeper Bernd Leno.
Arsenal dominated the first half and could have been further ahead at the interval but for some wayward finishing - especially from Lacazette, who blazed high over the crossbar from close range.
"We were not getting near enough to their players, who were playing quick football between the lines with one or two touches".
"The second goal was a frightful mistake where we don't have to take such a risk", a rather downcast Saints manager Ralph Hassenhuettl told reporters. "That reaction was good, but probably not enough".
