The Gunners were in the drivers' seat of the game, winning 2-0 and looking comfortable.
But a mistake while passing out the back allowed Cleverley to get one back, while Roberto Pereyra equalised from the penalty spot.
And Cleverley admits to being surprised at how Arsenal approached the game as it went on.
"I feel like we were well organised from their goal kicks," he said to reporters.
"It is something we worked on all week. We weren't surprised they tried to play like that.
"It was just more of a surprise they didn't adapt during the game and they were pretty stubborn with it."
