The burly striker started his career with the Magpies and shone as they gained promotion back to the Premier League in 2009/10 before performing well in the top tier for the opening half of the following campaign.
He then made an ill-fated £35m move to Liverpool before eventually heading for West Ham for around half that figure, but his spell in east London has been hindered by injuries.
However, reports claim that the Hammers are predicting a move from Newcastle to lure their cult hero back to St James’ Park, and are only willing to do business for £18m.
Such a sum is lofty for a player with Carroll’s fitness concerns, even if he can be a fearsome centre-forward on his day.
The 26-year-old made 29 appearances altogether through the 2013/14 and 2014/15 seasons.
