Speaking at a news conference, ahead of his club's Champions League playoff first leg against Italians Udinese at the Emirates Stadium on Aug 16, Wenger said, "We have lost a world class player and we are sad about it, we did try to keep him."
And added, "In the end we had to respect the desire of the player. This club is 125 years old this season and many big players have left the club and the club has gone on. So we want to show we have the strength and the unity to fight as ever."
But the move from his former captain, has not left Wenger and he understands that it makes sense for Fabregas. He said, "He comes back to Barcelona, he was educated at Barcelona. His grandfather was part of the (club) committee."
And added, "He was virtually brought up at Barcelona's creche. On top of that, he is going to a club that has the best team in the world at the moment. So from that point of view, we can also understand that it has nothing to do with money, it is an affair of the heart."
Fabregas, on the other hand was deeply appreciative of Wenger's contribution to his career. Speaking at almost the same time as Fabregas, but in a different part of the world, Fabregas said, "I'll never have enough words to say what I think about Arsene Wenger and if Arsenal wants to be the club they are they always have to be under his control."
And added, "He is the best, everyone respects him and he will always be the best person I met in football. He was like a father figure to me. If today I am here with you, living my dream, then it's greatly due to him."
He was speaking to the Spanish media.
Speaking about his regrets at Arsenal, the 24-year old said, "My biggest regret is that we won only one FA Cup and the biggest regret I will have in my career is that I did not lift a trophy as an Arsenal captain, but I am sure they will be a strong team again."
And added, "I will always be an Arsenal fan because what they have done for me is unbelievable and I will never forget it."
