It is understood a contract is in place for the 35-year-old to stay and boss Jose Mourinho certainly wants him to, judging by his comments.
"This team has a lot of growing to do," said Mourinho during his media session pre-Bournemouth.
"The next transfer window will bring us to a different level because I will bring in a few players. Zlatan will be fundamental in the second year. I think he will stay."
