In 2014 - Wenger said Fabregas wanted to return, he was informed that he might go to Chelsea, but that we didn't need any offensive players after signing Ozil.
Wenger said he believes that a deal was struck in early 2014, but Fabregas said he hadn't even decided to leave Barcelona until the final game of the season after they lost the title.

In 2020 - Wenger said in a podcast - 'It was a general guidance from me to have that, to make the players [realises] 'Look if you go out here, you don't come back'."
In a 2020 chat on the Arsecast podcast, Fabregas revealed: "My agent Darren [Dein] spoke to Arsene. He didn't give him an answer to be honest, then we had to wait one full week to see if Arsenal responded."
"Definitely this was my first option, in my mind I'm telling everyone I'm going to Arsenal, this is what I want. Not Arsene, [Ivan] Gazidis or anyone said anything for a week.
"I didn't want to be a beggar. We told them once, they know the situation if in one week they hadn't said anything... straightaway I knew that probably they didn't want me back.
They could have said after three hours they didn't want me back so I could have spoken to other teams. They waited the whole week without giving me a response and still since then, no response ever."
