I believe the Chelsea or Maresca - Jackson relationship in my opinion is already a sour one, and even If Jackson stay back, I think he'll still be surplus to requirements and might even be behind Guiu in the pecking order.
Dude was given lots of opportunities but he couldn't do anything with them. When he was the main man, what could he do with those chances that were created for him. Dude is poor in front of goal and I don't blame him for not wanting to comeback. He's not even in the two strikers at the club and will be warming the bench immediately Delap is back from injury. Chelsea only called him back out of desperation and not like he's a good choice. I backed this guy for like years and still he couldn't improve. I don't want him at my club, we have lots of attacking threats, any of them can play as false 9 and still the goals will be coming in.
