The left-back was seen exchanging shirts with Robin Van Persie at half-time during Arsenal's 2-1 loss to Manchester United last year. This act was tagged as unacceptable by many Arsenal fans and legends and many supporters hated him for that. Santos feels what he did was just out of love and nothing more.
"You guys have a different culture than me and it is still very hard to understand why people hold this grudge over me.
"The relationship was very good until the incident with Van Persie. I have apologised and moved on.
"I have all my respect to the fans of Arsenal. Hopefully soon I will be back and giving them many happiness."
Speaking on his decision to go on loan and the benefits of the move he said,
"The idea is to go there, play well and be able to come back strong. Do I have a future at the club? For sure. This is a loan deal and after this season we will see where everythingstands.
"I always wanted to stay here until the end of my contract. This is a club where I feel comfortable and honoured to play. However, when the club acquired another left-back it was clear to me that I will not play. I need to play, get my confidence back and Gremio is a good platform for this.
"I talked [with Wenger] and we decided together this would be a good chance for me to get on top of my game. He gave me a hug and told me Arsenal would always welcome me back with open arms. He did [want me to stay] but he wanted to see me happy and if I am not performing all the time, then I am not happy."
