While he admitted being flattered by David Moyes' attempts to persuade him to move to Manchester United, he revealed that Martinez's charm offensive had ultimately proved more successful.
Baines told the BBC's Football Focus: "I talked about it a lot with the manager (Martinez). We had a lot of conversations because something seemed to be going on and he kept me informed.
"He was adamant that he wanted me to stay here. It was flattering really, to have your old manager wanting to take you with him and your new manager really wanting to keep you."
