Chelsea hero Mario Melchiot thinks the club stood by their philosophy surrounding ageing players after Willian decided to leave Stamford Bridge.
The 31-year-old Brazilian wanted a three-year extension but Chelsea would only offer two years.
Willian is now expected to join Arsenal on a three-year deal, but Melchiot believes the Blues made the right decision to stick to their guns.
"Don't get me wrong, they always produce some talented players.
"But when you look at Chelsea, they tried to hold onto a certain key thing now where players, when they get to a certain age, they always consider 'do we really need this player?'
"I think with Willian, they made it clear. They negotiated a deal and it didn't come the way Willian wanted it to.
"Arsenal were listening to that and tried to pinch him right before anything could happen."
