Arsene Wenger named a young side for the opening game, but the Frenchman could make plenty of changes to give other squad members playing time as they build up their match fitness.
Club-record signing Lacazette will be eyeing a first Arsenal start after beginning the first game on the bench and then coming on late to wrap up the win with a debut goal.
The former Lyon man looked sharp in the brief cameo he was given, and although he played just behind Olivier Giroud, that did not prevent him getting into the box and posing a real threat.
He could replace Danny Welbeck, who started on Thursday but missed a penalty before making way in the second half.
Per Mike Anstead at MailOnline, Arsenal may have to do without Theo Walcott, who appeared to pick up an injury against Sydney FC:

Youngsters Reiss Nelson and Cohen Bramall will also be be hoping for further game time after impressing in the opening game.
Nelson was heavily involved in the first half, looking bright and posing problems for the hosts, while ESPN FC's Mattias Karen feels Bramall, who joined from non-league Hednesford Town in January, could prove to be an astute signing by Wenger:

Cohen Bramall causing all kinds of problems with his pace (and surprisingly good technique). He could prove quite the bargain.2017-7-13 10:26:14
Elsewhere, experienced stars such as Alex Oxlade-Chamberlain, Aaron Ramsey, Granit Xhaka and Alex Iwobi were all left out of the starting lineup and could come into contention on Saturday.
