Arsenal have reportedly withdrawn their contract offer for the Welsh global who has been at the club since 2008. Both players scored a goal and had an assist off the bench - the first time in Premier League history two subs have achieved that feat in the same game for the same team.
Lacazette and Aubameyang scored two goals each, with Aaron Ramsey netting the other one for the visitors.
It only took Ramsey a matter of seconds to put Arsenal 3-1 up with a sweet finish courtesy of an Aubameyang's assist.
Liverpool is being said as the most favourite destinations for Aaron Ramsey as Jurgen Klopp's interest in him is no more secret and given their failure to sign Nabil Fekir from Lyon in the last summer's transfer window, this deal could get a green signal.
Trump's 2nd Supreme Court pick Kavanaugh sworn in
Kavanaugh's nomination process has been plagued in recent weeks by sexual misconduct allegations made by three women. Support from Collins and Manchin would give Kavanaugh at least 51 votes, assuming no one else changes their stance.
The Welshman will be free to hold talks with clubs outside England in January and sign a pre-contract with a view to leaving Arsenal at the end of the season. The England global made the switch from the Emirates Stadium to Anfield past year in what turned out to be an excellent move for the player, and former team-mate Aaron Ramsey could be set to tread the same path. I think we are in the first competition in the war.
With Arsenal heading into the worldwide break on the back of a positive run of results there is talk they could now finish back in the top four - if not challenge for the title - having missed out on Champions League football for the last two seasons. We will enjoy it, we are working well and we want to continue like this.
Manchester City, Liverpool and Chelsea are all on 20 points after eight games played, with Arsenal on 18 in fourth place.
