The fact remains you are completely making this up. There's just no indication that this might happen, that Essien might have the mindset you are thinking he has. Its complete speculation. There is a very small chance of it happening, but it is unlikely, and not something we should factor into any equation of players coming in and going out this summer.
I read on another topic here that the Sun had run with that Lampard will leave because he walked to four corners of the pitch so I really wouldn't be surprised, unless of course Layla made that up, don't see why she would have though.
