Arsenal manager Arsene Wenger was delighted with the way his players responded following their hard-earned 1-1 draw with Manchester United at Old Trafford in the Premier League on Saturday.
The Gunners were 1-0 down with a minute remaining after Juan Mata's strike midway through the second half, but substitute Olivier Giroud climbed off the bench to snatch a point for the visitors.
Wenger hailed the impact of Giroud as well as fellow replacement Alex Oxlade-Chamberlain, who provided the assist for the equaliser, and was generally pleased with the character shown by his players.
"We had a good response and once again the players that came on made a massive difference," he said.
"Chamberlain and Giroud were involved in the goal and it was great goal, just before the end.
"When you are 1-0 down and you come back to 1-1 it feels like a victory, you are happy. We lacked a bit of sharpness, what it is down to, I don't know.
"Last year we would have lost this game, maybe, and today we didn't so we have improved on that front."
However, the Arsenal boss is targeting improvement in his side's performance ahead of their crucial UEFA Champions League showdown with Paris Saint-Germain at the Emirates Stadium in midweek.
The Gunners will take a giant step towards topping their group with a win and Wenger is expecting a similar contest to that at Old Trafford on Saturday.
"Hopefully we can move on with some wins, we have a big game on Wednesday against Paris Saint-Germain and that will be the same intensity," he added.
"I am convinced that we will be better on Wednesday."
