Under the "ABBA" penalty shoot-out trial, Arsenal won 4-1, as Blues goalkeeper Thibaut Courtois and record signing Alvaro Morata missed from 12 yards.
The 26-year-old was not heavily involved but hit the post with a curling effort in the first half and, given the eventual service of Mesut Ozil plus dynamism of Aaron Ramsey and Alexis Sanchez, could flourish in north London.
"I can't tell you that at the moment", he said.
"I believe Man City will win it".
"(Kolasinac) came on very well.
Mertesacker got some intriguing answers from Wenger - it turns out the manager's favourite word is "love", and he would play Zorro in a movie if he could.

Alvaro Morata scores his first goal for Chelsea in defeat to Burnley

"His power will play a part but it's not the only thing".
"(PSG) are looking for (Kylian) Mbappe, that's what I read in the papers.
Olivier Giroud, meanwhile, starts from the bench as Lacazette received the nod from Wenger to start the season as first-choice centre-forward. Let's hope that the side which beat Chelsea on the weekend can have similar success against the Foxes in the Premier League. Not enough competition for places is detrimental also. "They're too important", BT Sport pundit Jenas said.
"Today was encouraging, but nothing more". We want to find a good balance between the confidence we can get out of this game and the urgency that every Premier League game demands.
"Then we need to transform the quality of the preparation into points and that is, of course, a pragmatic view, but what matters is we win the next game and start in a strong way, which we didn't do a year ago".
