Arsenal manager Arsene Wenger believes his side got a little ahead of themselves in the Champions League Round of 16 first leg.
The Gunners lost 3-1 to Monaco at the Emirates Stadium in late February which ultimately led to their elimination from Europe's premier club competition despite a 2-0 win on French soil on Tuesday.
Arsenal almost pulled off a miracle in the return bout at the Stade Louis II but came up short on the away-goal rule which Wenger was left to rue.
"Football is not a fairytale, it is a matter of being realistic and being clinical, maybe a bit lucky as well, maybe that is part of the game," said the Gunners boss after Olivier Giroud and Aaron Ramsey were on target in the principality.
"If you take a look at the shots on target in the two games, they were well rewarded, and were very clinical.
"They really surprised us in the first leg when we were too sure of ourselves on the night."
