Here's all of Arda's quotes from the press conferance
"Messi is not only the best now, he's the best ever. Ronaldo is special, but there will never be anyone like Messi."
"I'm at the best club in the world now. I want to thank Simeone and everyone at Atletico. I'm also here at Barça thanks to them."
"We know that Barça is more than a club. Everybody who knew me as a kid knew I've always wanted to play here. It was my dream."
"I received many offers, but I put them all away when Barça called. If Barça wants you, you have to reject all others."
"Replacing Xavi? Nobody can replace such a great player. He was an idol around the world. I'm a different player."
"I'll play alongside the best players iof the world, at the best stadium of the world... Competition is tough, but I'm here to enjoy."
"Luis Enrique called me. It made me feel happy. I liked it that he got in touch to tell me he wanted me at his team."
"I saw Luis Enrique scoring a really nice goal in Istanbul. I was a ballboy at that game. And now he's my coach..."
"I've always been a fighter. I can play good or bad, but I always try to do the best I can."
"I've dreamed all my life to get here. I'll have to adapt to a new system, it won't be easy. I want to become a better player."
"I think Messi, Suarez, Neymar, Iniesta and I can play together all five. Why not...? I think it will happen this season."
"Shirt number? That's not important to me. I will make a decision after I've talked about it with my teammates."
"Luis Enrique called me after the deal was done and Iniesta sent me a message to welcome me, liked that a lot."
"Just putting on the Barça shirt already made me nervous..."
"Row with Neymar? There was always a lot of tension in the games, but that's the past. What happens on the pitch, stays on the pitch."
"Loan until end Fifa ban? That's not an option. I will use these six months to adapt to the club and the city."
