Arsenal will face West Ham today in the London derby.
Ljungberg joined West Ham from Arsenal this summer.
“You don’t bear grudges with Freddie because I know he’s an honest guy, I will always love Freddie, no matter what he says because I have gone through difficult and many things with him,” said Wenger.
“I know he’s not a guy whose mischievous. Today he changed his mind, fair play to him.”
Wenger added: “He got a three-year contract at the age of 30 and he had an opportunity to play.
“Freddie was always a very important player here, he was a fantastic player for Arsenal and he decided in the end to go for a new challenge. I respect that.”
