The Old Trafford defender said: "Robin conducted himself the way we expected him to. He's a classy guy and he did well.
"You have to understand that fans are going to have their opinions and they are going to voice them.
"He didn't come here unaware that people were going to be resentful. When they go home and take stock of what he's achieved this season, he has come in and won a trophy in his first season.
"That was his aim and that was the reason why he came to us.
"In the cold light of day, the Arsenal fans will understand."
